    3 Min Read

    Texas Instruments introduced the industry’s first 650V three-phase GaN IPM for 250W motor drive applications. The new GaN IPM addresses many of the design and performance compromises engineers typically face when designing major home appliances and heating, ventilation and air-conditioning (HVAC) systems.

    The DRV7308 GaN IPM enables more than 99% inverter efficiency, optimized acoustic performance, reduced solution size and lower system costs. It is on display at the Power Electronics, Intelligent Motion, Renewable Energy and Energy Management (PCIM) Conference, held June 11-13 in Nuremberg, Germany.

    “Designers of high-voltage home appliances and HVAC systems are striving to meet higher energy-efficiency standards to support environmental sustainability goals around the world,” said Nicole Navinsky, Motor Drives business unit manager at TI. “They are also addressing consumer demand for systems that are reliable, quiet and compact. With TI’s new GaN IPM, engineers can design motor driver systems that deliver all of these expectations and operates at peak efficiency.”

    Improve system efficiency and reliability with TI GaN

    Worldwide efficiency standards for appliances and HVAC systems such as SEER, MEPS, Energy Star and Top Runner are becoming increasingly stringent. The DRV7308 helps engineers meet these standards, leveraging GaN technology to deliver more than 99% efficiency and improve thermal performance, with 50% reduced power losses compared to existing solutions.

    In addition, the DRV7308 achieves industry-low dead time and low propagation delay, both less than 200ns, enabling higher pulse-width modulation (PWM) switching frequencies that reduce audible noise and system vibration. These advantages plus the higher power efficiency and integrated features of the DRV7308 also reduce motor heating, which can improve reliability and extend the lifetime of the system.

    To learn more about the benefits of GaN technology, read the white paper, “How three-phase integrated GaN technology maximizes motor-drive performance.”

    Advanced integration and high power density reduce solution size and costs

    Supporting the trend of more compact home appliances, the DRV7308 helps engineers develop smaller motor drive systems. Enabled by GaN technology, the new IPM delivers high power density in a 12mm-by-12mm package, making it the industry’s smallest IPM for 150W to 250W motor-drive applications.

    Because of its high efficiency, the DRV7308 eliminates the need for an external heatsink, resulting in motor drive inverter printed circuit board (PCB) size reduction of up to 55% compared to competing IPM solutions. The integration of a current sense amplifier, protection features and inverter stage further reduces solution size and cost.

    To learn about designing more efficient, compact motor systems, see the GaN IPM page on TI.com.

  • Infineon Technologies Pioneering in Semiconductor Industry with Comprehensive Product Carbon Footprint Data

    Infineon Technologies Pioneering in Semiconductor Industry with Comprehensive Product Carbon Footprint Data

    3 Min Read

    Infineon Technologies AG will provide customers with comprehensive Product Carbon Footprint (PCF) data, taking a pioneering role in the semiconductor industry. The company is committed to eventually providing PCF data for its entire product portfolio, starting now with about half of its portfolio.

    The initiative will empower customers to advance their own sustainability goals and reduce their carbon footprint effectively along the entire supply chain. The Product Carbon Footprint is a metric that quantifies the greenhouse gas emissions associated with an individual product, allowing the comparison of different products’ climate impact. Infineon will share more insights with customers at the upcoming PCIM trade fair in Nuremberg, Germany, from 11 to 13 June 2024.  

    “By providing comprehensive Product Carbon Footprint data, we are driving the vision of a net-zero society and empowering our customers to reduce carbon emissions even more effectively,” says Elke Reichart, Member of the Management Board and Chief Digital and Sustainability Officer at Infineon. “Infineon is taking a leading role in carbon transparency by committing to include the entire product portfolio over the coming years. This underlines our ambition to be a leader not only in terms of technology, but also sustainability.”

    The specific data Infineon provides on its individual products is essential for the growing number of customers who want to increase transparency on their own carbon footprint. Moreover, it supports informed decision making to leverage additional potential for reducing emissions along the value chain.

    In the absence of established industry standards, Infineon has developed a robust methodology to calculate the Product Carbon Footprint, incorporating customer needs and best practices. Infineon includes emissions from raw materials and supplies, its own manufacturing processes, manufacturing partners and transportation to the customer (“from cradle to gate”).

    This means that the Product Carbon Footprint reported by Infineon covers scope 1 and 2 emissions as well as scope 3 emissions from suppliers and manufacturing partners, all the way to the customer’s gate. The Product Carbon Footprint is expressed in kilograms of carbon dioxide equivalent (kg CO 2e).

    Infineon has published the assessment of reference product families on the Infineon website.

    Driving transparency goes hand in hand with Infineon’s strong commitment to decarbonization and digitalization. Infineon’s products make a major contribution to the global energy transition and thus to a net-zero society. They are used in solar and wind power plants, electric cars and increase energy efficiency in numerous applications, including AI data centers. Over their lifetime, the company’s chips overall save 34 times the amount of CO 2e emitted during their production.

    Breaking the carbon footprint down to the product level is another major milestone in Infineon’s sustainability journey. Infineon has already pledged to achieve carbon neutrality by 2030 for direct and indirect emissions (scope 1 and 2). Last year, the company additionally committed to setting a science-based target encompassing supply chain emissions (scope 3) as well.

    Benefits:

    • Highest Creepage Distance Available for SiC Top Side Cooled Packages
    • Higher System Power Density with Optimized PCB Layouts
    • High Volume Manufacturing Capability with Surface Mount Footprint

    What’s New? Advantages of New Top Side Cooled Packages

    Most standard surface mount discrete power semiconductors remove heat through the bottom of the device by making direct contact with the power circuit board (PCB), which utilizes a heat sink or cooling plate attached underneath. This method is common across many different power electronics applications, particularly when size and weight requirements do not limit PCB mounting and heat sinks.

    Top side cooled (TSC) devices, on the other hand, dissipate heat through the top side of the package. Inside TSC packages, the die sits upside down in the upper portion of the package to allow heat to flow directly to the top surface. Generally, TSC devices are best suited for high-performance applications such as automotive and e-mobility systems where high-power densities, advanced thermal management solutions, and small footprints are essential. Within these applications, TSC devices help address cooling requirements by enabling maximum power dissipation and optimizing thermal performance.

    TSC designs also allow for dual-side usage of the PCB since the bottom board surface is no longer needed for the heatsink interface. Removing the heatsink from the thermal path not only creates an improved overall system thermal impedance; it also allows for automated assembly, which can increase manufacturing throughput for a more efficient and cost-effective solution.
