In the automotive industry, the introduction of xEV = HEV (Hybrid Electric Vehicle), PHEV (Plug in Hybrid Electric Vehicle) and BEV (Battery Electric Vehicle) is accelerating to develop vehicles with low environmental impact in line with the trend toward carbon neutrality. As this becomes more familiar to the public, xEV Inverters need to be smaller and thinner, and there is strong market pressure to reduce costs, so it is necessary to reduce the number of parts. Recent 6in1 SiC (Silicon Carbide) modules for xEV have added product value by incorporating snubber capacitors within the module. This integration requires attention to test conditions and some techniques are needed.

In addition, by mounting SiC KGD (Known Good Die) in parallel inside the module, the total current capability is increased, and the number of DIB parts (especially relays) increases accordingly. Therefore, we offered AC only, DC only, and AC/DC indexed parallel in one ETS-88TH DUO to provide a more flexible solution.
