Toyota unveiled its plans Wednesday to trial a new hybrid system using silicon carbide power semiconductors that could find its way into hybrids and EVs.
The trial will compare the new silicon carbide semiconductors with silicon units currently found in many a hybrid's, FCV's and EV's power control unit, which are linked to a 20 percent loss in overall electric power. The aim is to increase powertrain efficiency by mitigating said losses through the new semiconductors.
The test subjects will be a Camry hybrid prototype and a fuel-cell bus. The bus trial began in early January, when Toyota started data collection on a setup featuring SiC diodes in the FCV's voltage step-up converter. Meanwhile, the Camry — whose SiC components are in both the hybrid's voltage step-up and inverter — will hit the road for a year beginning early next month. Both tests are being carried out in Toyota City, Japan.
Toyota hopes to have the SiC technology — developed in a partnership with Denso Corporation and Toyota Central R&D Labs, Inc. — ready for practical use as soon as possible.
