is an induction motor. In FIG. 1, the PWM inverter 4 chops the DC power no at a frequency of usually several 100H+, converts it into a square wave pulse voltage, and controls the pulse to generate a predetermined three-phase AC voltage at one output terminal U, V, Wjζ. is generated and energizes the induction motor 5, but an intermittent current flows on the DC side of the PWM inverter 4 due to the above-mentioned chopping.

There is a risk of malfunction, which is extremely dangerous for vehicle operation.For this reason, in the past, in order to increase the filtering effect of the filter circuit in the commercial frequency range, the resonant frequency of the filter circuit was set much lower than the commercial frequency, and the DC power was turned off. On the other hand, in order to lower the resonance frequency of the filter circuit, the capacitance of the filter capacitor 3 or the filter reactor 2
It is necessary to increase the inductance of Iζ
