Abstract:
1. A DC-DC converter system of an electric vehicle, the DC-DC converter system being arranged between a battery acting as a DC power source and first and second motors selectively acting as a motor or a generator respectively, the DC-DC converter system comprising: first and second inverters configured to supply power to the first and second motors or receive power from the first and second motors, respectively; a DC-DC converter configured to boost DC voltage from the battery and supply the boosted voltage of the battery to the first and second inverters and boost DC voltage from the first and second inverters and supply the boosted voltage of the first and second inverters to the battery; and a control unit configured to control an output voltage supplied to the first and second inverters by switching the DC-DC converters after generating a voltage command, wherein the control unit controls the DC-DC converter by:
