This paper analyses and designs a new soft-switching single-phase high power factor voltage-doubler rectifier. The proposed rectifier combines the conventional pulse-width-modulation technique, soft commutation technique and instantaneous average line current control to promote the circuit performance. Comparison with conventional boost rectifier, the proposed rectifier own double voltage function...
This paper proposes a high performance single-stage transformer isolated AC/DC converter to give high input power factor and low current distortion on the input side and provide stable and low ripple dc voltage on the output side. The proposed AC/DC converter only employs four switches to perform the power factor correction in input side and provide regulation of the output dc voltage magnitude. Thus,...
This paper analyses and designs a zero-current-switching single-phase high power factor voltage-doubler rectifier. The proposed rectifier combines the conventional pulse-width-modulation technique, soft commutation technique and instantaneous average line current control to promote the circuit performance. Comparison with conventional boost rectifier, the proposed rectifier own double voltage function...
This paper proposes a new single-phase high power factor rectifier, which features regulation by conventional PWM, soft commutation and instantaneous average line current control. A zero-voltage-switching pulse-width modulation (ZVS-PWM) auxiliary circuit is configured in the presented ZVS-PWM rectifier to perform ZVS in the main switches and the passive switches. Furthermore, soft commutation of...
