Abstract
A chopper power supply of the invention includes a bridge arm constituted by two switching sections in series and receiving a DC voltage. Each switching section includes switching means in parallel with a capacitor, the switching means being controlled so as to supply an AC voltage to a load. A pulse current source is connected to the load, the pulse current source being constituted by an LC-type circuit dimensioned so that the current flowing through the circuit is delayed by .pi./2 relative to the voltage applied to the load so as to deliver current pulses for alternately charging and discharging each of the capacitors on the edges of the AC voltage.
