| Abstract |
This paper presents a 10kW three phase bidirectional on-board battery charger for use as a V2Ginterface in electric vehicles (EVs). The interface to the grid in the on-board charger is a three phaseIGBT-based boost converter, being in charge of the power factor correction (PFC). The interface to thebattery is an isolated dual active bridge (DAB) converter based on the silicon carbide (SiC) JFETs.1200V rated SiC JFETs enable both the operation at high voltage values in the DC link (above 500V)and high switching frequencies in the range from 50 to 150 kHz. Both high converter efficiency andcompact converter design can be achieved thanks to the application of these wide band gapcomponents. The control algorithm where PFC stage can control the flow of reactive power and theDAB the flow of active power between traction battery and the grid is presented and analyzed. |
