This paper presents single stage series load resonant ZVS-PWM high frequency inverter which operates one diode conduction mode and critical ZCS PFC rectifier for induction heating (IH) applications. This single stage inverter is composed of a single phase PFC rectifier operating at one diode conduction mode and asymmetrical ZVS-PWM high frequency resonant inverter without the interlink bulky electrolytic...
A novel three-phase single-stage boost power factor correction (PFC) converter topology is presented. The converter operates in discontinuous conduction mode (DCM), and the PFC function is realized easily with the peak of input current following input voltage automatically which is the same as that of the traditional single switch three-phase boost PFC. Compared with the single switch three-phase...
A novel three-phase full-bridge power factor corrector is presented in this paper. The corrector operates in discontinuous conduction mode (DCM), the peak of input current follows the input voltage automatically. It can achieve zero-voltage-switching (ZVS) for the leading-leg switches and zero-current-switching (ZCS) for the lagging-leg switches without adding any auxiliary device. Due to the adoption...
A new push pull boost ac-dc or dc-dc single stage pulse width modulated (PWM) converter is proposed. The converter operates with zero voltage switching (ZVS), and continuous input current. It feature several merits such as single stage energy processing and good input current shaping. The converter topology also has zero turn-on loss even when used with hard switching. An auxiliary switch clamps the...
