  • onsemi Announced Availability of Nine New EliteSiC Power Integrated Modules

    onsemi Announced Availability of Nine New EliteSiC Power Integrated Modules

    3 Min Read

    onsemi announced the availability of nine new EliteSiC Power Integrated Modules (PIMs) enabling bidirectional charging capabilities for DC ultra-fast electric vehicle (EV) chargers and energy storage systems (ESS). The silicon carbide-based solutions will dramatically improve system cost with higher efficiency and simpler cooling mechanisms that can reduce size by up to 40% and weight by up to 52% compared to traditional silicon-based IGBT solutions.

    With more compact, lighter charging platforms, designers will have all the key building blocks that are needed to quickly deploy a reliable, efficient and scalable network of DC fast chargers that can charge electric vehicle batteries up to 80% in as little as 15 minutes.

    According to J.D. Power’s 2023 Electric Vehicle Consideration Study, nearly half of U.S. consumers note the reason for not purchasing an electric vehicle is the access to charging and the ability to do so quickly, to ensure the driving experience is as easy and seamless as with a traditional internal combustion engine (ICE) vehicle. In the U.S., the availability of EV chargers needs to quadruple by 2025 and 8x by the end of the decade to keep up with demand and ensure drivers have equitable access to public charging stations.

    In turn, this rapid increase in demand for electricity will also put a tremendous strain on current electrical grids, potentially overloading them. To mitigate this problem, bidirectional charging has emerged as a key solution to implement vehicle-to-grid which allows both regular battery charging and the ability to use an EV as an energy storage system to power your home when needed.

    This solution helps enable a DC fast charging network and vehicle-to-grid power transfer systems, addressing access and speed with its ability to recharge a vehicle faster than other methods that take hours or even days.

    onsemi offers the most comprehensive portfolio of PIMs to address the key topologies on the market. This gives designers the flexibility to pick the right PIM for power conversion stages in their DC fast charging or energy storage system applications. To accelerate the design cycle, advanced piecewise linear electrical circuit simulation (PLECS) models through our Self-Service PLECS model Generator and application simulation with the Elite Power Simulator of this portfolio will also be made available to designers.

    For each module, onsemi uses die from the same wafer to ensure more consistency and reliability so designers don’t have to use discretes from different suppliers, which can lead to varying performance results. In addition to its reliability, this module portfolio offers the following benefits:

    • Uses the Gen3 M3S SiC MOSFET technology which offers the lowest switching losses and highest efficiency in the industry
    • Supports key topologies such as multi-level T-type neutral point clamp (TNPC), half-bridge and full-bridge topologies
    • Supports scalable output power from 25 kW to 100 kW, enabling multiple DC fast charging and energy storage systems platforms including bidirectional charging
    • Industry-standard F1 and F2 packages with the option of pre-applied Thermal Interface Material (TIM) and press fit pins
    • Enables optimal thermal management, avoiding system failure due to overheating
    • Full SiC modules offer energy conservation by minimizing power losses, directly translating to cost and energy savings
    • Offers more robustness and dependability, ensuring consistent operations

    Infineon Introduced 4.5 kV XHP™ 3 IGBT Modules to Fundamentally Change the Landscape for Medium Voltage Drives

    2 Min Read

    The paradigm shift towards offloading complexity to suppliers and adopting smaller IGBT modules is evident in various applications. In response to the global push for downsizing and integration, Infineon Technologies AG introduced the 4.5 kV XHP™ 3 IGBT modules that will fundamentally change the landscape for medium voltage drives (MVD) and transportation applications operating at 2000 to 3300 V AC in 2- and 3-level topologies.

    Applications benefiting from the new devices include large conveyor belts, pumps, high-speed trains, locomotives, as well as commercial, construction and agricultural vehicles (CAV).

    The XHP family comprises a 450 A dual IGBT module with TRENCHSTOP™ IGBT4 and an emitter-controlled diode, and a 450 A double diode module with emitter-controlled E4 Diode. Both modules feature improved isolation of 10.4 kV. Together, they help to simplify paralleling and downsizing without sacrificing efficiency.

    Previously, complex busbars were required to parallelize switching modules, resulting in complicated design efforts and leakage inductance. The innovative design of the XHP family simplifies paralleling by conveniently placing the connections side by side. As a result, only a single straight busbar is required for paralleling. 

    The 4.5 kV XHP family also allows developers to reduce the number of units. Conventional IGBT solutions use multiple single switches and a double diode. With the new devices, however, designs can be reduced to two dual switches and a smaller double diode – a significant step forward in integrated drives.

    The combination of the XHP 3 FF450R45T3E4_B5 dual switch and the DD450S45T3E4_B5 double diode enables significant cost savings and a smaller footprint. For example, Infineon’s previous IGBT solutions required four 140 x 190 mm² or 140 x 130 mm² switches and one 140 x 130 mm² double diode. With the new XHP family, the components can be reduced to two 140 x 100 mm² dual switches and a smaller 140 x 100 mm² double diode.

    The IGBT modules FF450R45T3E4_B5 and DD450S45T3E4_B5 are available now. More information is available at www.infineon.com/XHP.
