  • WeEn Semiconductors Delivers Optimal Solution for Supercharging Modules

    WeEn Semiconductors Delivers Optimal Solution for Supercharging Modules

    5 Min Read

    As the “heart” of charging stations, the performance and reliability of charging modules are undeniably crucial. The popularization of the “super charging” concept has made long cruising range and short charging time become the selling points of more and more electric vehicles on the market.

    Recently, the newly released Chinese Standard GB/T20234-2023, which focuses on Part 4: High-Power DC Charging Interfaces for Electric Vehicle Conductive Charging Couplers, has been significantly revised to expand the voltage range to 1500Vdc and the corresponding current range to 1000A. Additionally, the standard now includes new provisions related to liquid-cooled charging stations.

    This means that in the future, higher-power megawatt-level charging stations will gradually become a reality. As long as your electric vehicle supports supercharging, it will be as convenient as refueling at a gas station.

    Charging Module Technology Analysis

    In fact, WeEn Semiconductors has long focused its business on the “low-carbon” track, while acknowledging that charging stations, as crucial supporting infrastructure, will evolve towards directions of higher power, greater efficiency, full liquid cooling, and comprehensive supercharging capabilities.

    WeEn’s latest research and development effort, the BYC100MW-600PT2, will enable customers to achieve designs for 40kW+ high-power, high-efficiency charging modules. The WND60P20W will offer customers a higher voltage design margin to meet the demands of more complex and challenging application scenarios, thereby supporting the rapid development of new energy vehicles and the achievement of low-carbon objectives.

    A charging module is essentially a power electronics converter that converts alternating current (AC) from power grid into direct current (DC) that can be stored in the battery of an electric vehicle.

    Charging module converters typically have a two-stage topology. The first stage is usually a three-phase Power Factor Correction (PFC), most often using the Vienna PFC topology. Its main function is to convert AC to DC and to correct the power factor.

    Solution for Supercharging Modules-2

    Figure 1: Vienna PFC Topology Architecture

    The second stage typically involves a DC-DC conversion, most often using the high-efficiency LLC topology. This stage primarily converts the high voltage DC output from the PFC (800Vdc) into a wide range of adjustable DC voltages from 200Vdc to 1000Vdc, to match the needs of different battery voltage levels. Additionally, the DC-DC stage also achieves electrical isolation from the power grid through a high-frequency transformer.

    Since the current charging modules are primarily used for delivering power to electric vehicles, the output rectification in the DC-DC stage commonly employs Fast Recovery Diodes (FRD). Benefiting from the negative temperature coefficient characteristics of Fast Recovery Diodes (FRD), and given that the LLC topology generally does not require stringent reverse recovery performance, FRDs are particularly suitable for use in charging modules that operate under high temperature and high current conditions.

    Benefiting from the negative temperature coefficient characteristics of Fast Recovery Diodes (FRD), and given that the LLC topology generally does not require stringent reverse recovery performance, FRDs are particularly suitable for use in charging modules that operate under high temperature and high current conditions.

    Solution for Supercharging Modules-3

    Figure 2: LLC DC- DC Topology Architecture

    Currently, the mainstream power ratings for charging modules on the market range from 20kW to 40kW. Superchargers typically operate by outputting through several charging modules connected in parallel. Therefore, to ensure that each module is not affected by others during startup, Oring diodes are essential. When functioning normally, these diodes are in a conducting state, primarily incurring conduction losses. Consequently, standard rectifier diodes with low forward voltage (VF) are the best choice.

    WeEn’s Professional Solutions

    WeEn semiconductors, including the BYC75W-600P for LLC secondary-side rectification and the Oring diode WND60P16W, have been mass-produced reliably for years in leading charging module manufacturers’ 30kW models. With the recent trend towards higher power in charging modules and the need to accommodate for the harsh operating environments of charging stations, we have responded to our customers’ actual needs by launching the BYC100MW-600PT2 for 40kW charging modules and the higher voltage-resistant WND60P20W, helping our customers solve practical application issues.

    #BYC100MW-600PT2 Features:

    • Maximum current up to 100A
    • Extremely low reverse leakage current
    • Optimal VF-QRR trade-off performance
    • Robust Eas capability

    #WND60P20W Features:

    • Maximum reverse voltage up to 2000 Vdc
    • Extremely low forward conduction voltage drop
    • Enhanced forward surge current capability
    • Robust Eas capability

    By comparing the specifications of the BYC100MW-600PT2 and BYC75W-600PT2, we find that the BYC100MW-600PT2 offers significant improvements in forward voltage (VF) while maintaining the same reverse recovery charge. As a result, it is more suitable for applications in 40kW high-power charging modules. Customers using the 40kW modules have observed an actual temperature rise reduction of 8°C to 10°C, which substantially enhances the thermal design of the system.

    In the context of charging station applications, considering that there is quite a distance from the output of the charging module to the high-voltage power battery, potentially up to 30-40 meters, it is important to note that at the moment the charging module begins outputting, stray inductance in the charging cable and capacitors within the system will oscillate. This causes the diode to endure a spike in reverse voltage. If the voltage exceeds the diode’s avalanche voltage, it will cause avalanche breakdown; if the diode’s avalanche energy is insufficient, it will be damaged.

    The WND60P20W is an enhancement of the existing WND60P16W product from WeEn Semiconductors, with the reverse withstand voltage increased to 2000Vdc while also improving its capability to withstand avalanche breakdown. The WND60P20W can meet the increasingly complex and harsh working environments of charging modules, providing greater safety margins for customer module designs.

    SIA and BCG Publish Global Chip Supply Chain Report

    5 Min Read

    The Semiconductor Industry Association (SIA), in partnership with the Boston Consulting Group (BCG), released a report on the global chip supply chain that projects the United States will triple its domestic semiconductor manufacturing capacity from 2022—when the CHIPS and Science Act (CHIPS) was enacted—to 2032. The projected 203% growth is the largest projected percent increase in the world over that time.

    The study, titled “Emerging Resilience in the Semiconductor Supply Chain,” also projects the U.S. will grow its share of advanced logic (below 10nm) manufacturing to 28% of global capacity by 2032, up from 0% in 2022. Additionally, America is projected to capture over one-quarter (28%) of total global capital expenditures (capex) from 2024-2032, ranking second only to Taiwan (31%). In the absence of the CHIPS Act, the U.S. would have captured only 9% of global capex by 2032, according to the report.

    While the report finds investments from the industry—facilitated by CHIPS incentives—are on track to reinvigorate semiconductor manufacturing in America and reinforce U.S. chip supply chains, it also identifies policy actions that will further strengthen supply chains, support R&D and chip design, grow the semiconductor workforce, and ensure CHIPS delivers maximum benefits to America’s economic and national security.

    The report also analyzes the efforts underway in other countries to incentivize chip production and innovation and the criticality of ensuring chip companies have open access to global customers and suppliers, among other topics.

    “Effective policies, such as the CHIPS and Science Act, are spurring more investments in the U.S. semiconductor industry. These investments will help America grow its share of global semiconductor production and innovation, furthering economic growth and technological competitiveness,” said Rich Templeton, Chairman of the Board at Texas Instruments and SIA board chair. “Continued and expanded government-industry collaboration will help ensure we build on this momentum and continue our next steps forward.”

    Other key report findings:

    • America’s world-leading 203% projected increase in fab capacity from 2022 to 2032 stands in stark contrast to its modest 11% increase from the previous decade (2012-2022), which ranked last among all major chip-producing regions, according to the SIA/BCG report.
    • The U.S. share of the world’s chip manufacturing capacity will increase from 10% in 2022—when the CHIPS and Science Act was enacted—to 14% by 2032, marking the first time in decades the U.S. has grown its domestic chip manufacturing footprint relative to the rest of the world. In the absence of CHIPS enactment, the U.S. share would have slipped further to 8% by 2032, according to the report.
    • The U.S. continues to lead the world in its overall contribution to the global value chain, with strong leadership positions in high value-added areas of semiconductor technology, including chip design, electronic design automation (EDA), and semiconductor manufacturing equipment.

    The report also finds industrial policies have the potential to create additional bottlenecks that increase supply chain risk. Certain segments of the semiconductor supply chain are at risk if incentive programs and large-scale industrial policies lead to non-market-based investment, which can result in overconcentration or oversupply. Government incentives should focus on enabling targeted, distributed, market-based investments.

    Further, the study highlights the ways in which governments and companies are taking concerted action to increase resilience. The U.S. CHIPS Act committed $39 billion in incentives for semiconductor manufacturing, plus a separate advanced manufacturing investment tax credit. The European Union unveiled the European CHIPS Act, China initiated the third phase of its Integrated Circuit (IC) Industry Investment Fund, and various other incentive programs have emerged in Taiwan, Korea, Japan, India, and around the world. In parallel, companies have made significant investments, in both established and new regions. The report projects around $2.3 trillion in capex in 2024-2032, compared to $720 billion in the decade prior to enactment of the CHIPS Act (2013-2022).

    Despite the progress made to strengthen U.S.-based semiconductor manufacturing, additional government policy actions are needed to help ensure America stays on track to address lingering supply chain vulnerabilities and grow its share of fabrication capacity, while also increasing its strength in areas such as advanced logic, design, EDA, and equipment in the face of growing global competition.

    “The CHIPS and Science Act has put America on course to significantly strengthen domestic semiconductor production and R&D, but more work is needed to finish the job,” said John Neuffer, SIA president and CEO. “We look forward to working with government leaders to advance policies that broaden the STEM talent pipeline, invest in scientific research, promote free trade and access to global markets, and expand and extend critical CHIPS incentives.” 

    The CHIPS Act’s manufacturing incentives have sparked substantial announced investments in the U.S. In fact, companies in the semiconductor ecosystem have announced more than 80 new projects across 25 U.S. states—totaling nearly $450 billion in private investments—since the CHIPS Act was introduced. These announced projects will create more than 56,000 jobs in the semiconductor ecosystem and support hundreds of thousands of additional U.S. jobs throughout the U.S. economy.
