Abstract :
A single-phase PWM (pulse-width-modulated) current source power converter with a sinusoidal input current is considered. To smooth the DC current in the reduced DC inductance, an LC parallel resonance circuit (tank circuit) is inserted in the DC side of the converter. The proposed converter can supply the constant DC current to a load. Experimental and analysis results show that the tank circuit contributes to the achievement of the smoothing DC current and the decrease of the DC inductance. The steady-state and the transient characteristics of the converter are given
