A ZCS-PWM interleaved boost rectifier with high power factor is proposed in this paper. The pulse-width-modulation technique and soft commutation technique are used in the proposed rectifier to promote the circuit performance. The proposed circuit includes two boost converter which are operated at interleaved mode to increase the output power and reduce the input ripple current. A ZCS-PWM auxiliary...
This paper analyses and designs a ZCS-PWM single-phase high power factor interleaved boost rectifier. The proposed rectifier combines the conventional pulse-width-modulation technique and soft commutation technique to promote the circuit performance. The proposed rectifier uses two boost rectifiers with interleaved operation to increase the output power and reduce the output ripple current and input...
This paper analyses and designs a zero-current-switching single-phase high power factor transformer-isolated voltage-double boost 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 transformer-isolated boost rectifier,...
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 dc power supply system to give high power factor and low current distortion on the rectifier side and provide stable dc voltage on the isolated dc/dc converter side. The proposed dc power supply system uses a new ZVS strategy to get ZVS function. Besides operating at constant frequency, all semiconductor devices operate at soft-switching without additional voltage stress. A significant...
