Infineon launches EasyPACK C SiC power modules for EV charging and storage

Infineon Technologies has introduced a new line of SiC power modules within its EasyPACK C family, specifically designed for high-power industrial applications such as fast DC EV charging, megawatt charging systems, energy storage, and UPS equipment. These modules are equipped with Infineon’s 1200 V CoolSiC MOSFETs G2 and .XT interconnection technology, which work together to enhance efficiency and prolong operational lifespan.

This latest release highlights the ongoing transformation of power electronics architectures through the adoption of silicon carbide, offering notable efficiency enhancements and reliability advancements in electrification and renewable energy systems, as noted by eeNews Europe readers.

Enhanced Power Density and Longevity

The EasyPACK C series is tailored for systems operating under fluctuating loads and challenging conditions. Infineon claims that these new modules can achieve over 30% higher power density and up to 20 times longer lifespan compared to previous CoolSiC MOSFET generations. Moreover, they boast a roughly 25% reduction in RDS(on), leading to decreased conduction losses and overall system power usage.

Furthermore, the updated EasyPACK C housing offers improved layout flexibility and supports higher-voltage configurations, ensuring scalability for future applications. By incorporating Infineon’s .XT interconnection technology, the modules enhance reliability in the face of demanding thermal and electrical cycling conditions, a critical feature for EV fast-charging stations and industrial storage systems with extended operational requirements.

Thermal Enhancements and Mechanical Innovations

Infineon has engineered these new modules to withstand overload switching temperatures up to Tvj(over) = 200°C. The addition of PressFIT pins doubles the current-carrying capacity, reduces PCB temperatures, and simplifies assembly processes. With a new high-temperature plastic housing and silicone gel, the modules can operate continuously at temperatures up to Tvj(op) = 175°C. They also provide 3 kV AC isolation for one minute, ensuring reliable performance in demanding industrial environments.

Collectively, these enhancements contribute to increased system efficiency, improved thermal stability, and extended operational lifetimes, addressing the needs of infrastructure operators seeking to minimize service intervals and optimize return on investment.

Infineon Technologies continues to drive innovation in the power electronics sector, offering solutions that cater to the evolving demands of high-power industrial applications and supporting the transition towards more efficient and reliable energy systems.
