An electric motor vehicle having a drive system comprises a controller including an inverter device. The inverter comprises first and second series of semiconductor switches which is arranged in parallel with a power source. When a key switch provided between the power source and the first series of the semiconductor switches is open in a stop mode of the vehicle, a signal is given to a control terminal of only the second series of the semiconductor switches to prevent a short circuit of a main battery.
