Abstract: In an electric vehicle, a power supplier includes a software type condenser charging circuit and a hardware type condenser charging circuit. The software capacitor charging circuit operates when a controller controls the software type condenser charging circuit while monitoring a voltage between opposite ends at an initial charging stage. The hardware type condenser charging circuit is operated when the controller controls the hardware type condenser charging circuit without monitoring the voltage between the opposite ends of the DC-link condenser or by direct switching manipulation of a user.
