<P>PROBLEM TO BE SOLVED: To provide an electric vehicle control unit which has redundancy and can be miniaturized. <P>SOLUTION: The electric vehicle control unit comprises a constant voltage constant frequency power supply composed of two groups of inverter circuits, a filter comprising a reactor and capacitor, and a transformer, as well as contactors provided by a pair between the two groups of inverter circuits and the filter. The filter composed of the reactor and the capacitor as well as the transformer are shared by the two groups of inverter circuits. While one inverter circuit in the group is penetrating, an auxiliary contact signal of the contactor stops gate start instruction for the other inverter circuit. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
