A new SiC Power Stack Evaluation Sample is available from Semikron. The Stack is rated to 100kVA at a switching frequency of 50kHz. This integrated assembly is driven by AgileSwitch Stack Electronics for use in a wide variety of systems including battery charging, solar energy and industrial applications.
Full Power Testing was performed at the rated specs to qualify the stack. A National Instruments GPIC and LabVIEW provided the user interface, pwm commands, and data capture.
The SiC Power Stack Evaluation Sample operates at 800Vdc with a peak output of 120Arms and supports a peak output power of 100kVA. The SiC Power Stack Evaluaion Sample features include:

AgileSwitch Stack Electronics (click on schematic to enlarge)
AgileSwitch Stack Electronics provide a platform for designing a smart power conversion module. Each set includes:
- One AgileSwitch Interface Board
- Up to 3 AgileSwitch 62mm, EconoDual or PrimePack Series Gate Drivers
The Interface Board controls the Gate Drivers via a 20 pin ribbon cable that sends bi-directional signals for controlling, monitoring, and protecting the IGBT/SiC MOSFET while providing the host with real time information for voltage, temperature and current measurements for each half bridge. Stack Electronics are rated from 50kW to 500kW.
