Verification of Fuel Efficiency Improvement by Application of Highly Effective Silicon Carbide Power Semiconductor to HV Inverter 2016-01-1230

A prototype power control unit (PCU) was manufactured using silicon carbide (SiC) power semiconductors (diodes and transistors), which have low power loss when switching on and off. This PCU was installed in a hybrid vehicle (HV) and driven on a test course and chassis dynamometer. The test results confirmed a fuel efficiency improvement of about 5 percent.
