Evaluation of Infineon HybridPACKTM Drive with Optimized Integrated Capacitor/Bus DC Link for High Performance Inverter Applications

The Infineon HybridPACK (exp TM) Drive module was previously evaluated using the SBE 700A186 (500muF and 500V) capacitor/bus DC link [1]. This testing demonstrated the importance of low equivalent series inductance to achieve maximum efficiency with fast switching at full voltage, but test equipment was limited to 50kW. Power testing up to 150kW is now performed using both 750V and 1200V IGBT versions of the HybridPACK (exp TM) Drive along with the 500V and 750V variants of the SBE capacitor/bus test kit. This work provides critical thermal data to establish a high performance inverter baseline that can be directly compared to silicon carbide modules which are planned for the HybridPACKTM Drive package in the near future.
