SiC Inverter Development Kit
HEK-INV-A
SiC Inverter Startup Kit for easy testing setup. Suitable for testing of variety of circuit structure and operation condition
A combination of SiC Three-Phase inverter with a controller, sample software, etc., so that it can be operated as a Three-Phase inverter simply by turning on AC100V for control. 6 unit of ROHM’s SiC-MOSFET are used to form a Three-Phase full-bridge inverter with max. rated power at 10 kVA. 24V control power supply and sample software are included.
SiC inverter set with minimal setup for immediate testing
Experiments can be performed immediately only with wiring to the power supply and load.
Various circuit configurations and conditions
Switchable between chopper or inverter operation with sample software by adjusting switching frequency, modulation factor, etc. at Controller board.
Software Development
Software development is possible too with HSDT-KIT-B (Power Elec. Development Kits)
