      • Analysis of a partial resonant AC-DC converter for high power and power factor

        Sang-Pil Mun,Si-Lyur Kim,ki-Yong Suh,Hyun-Woo Lee 전력전자학회 1998 ICPE(ISPE)논문집 Vol.- No.-

        This paper proposed that an Analysis of a partial resonant AC-DC converter for high power and power factor operates with four choppers connecting to a number of parallel circuit. To improve these, a large number of soft switching topologies included a resonant circuit have been proposed And, some simulative results on computer are included to confirm the validity of the analytical results The partial resonant circuit makes use of an inductor using step-down and a condenser of lose-less snubber. The result is that the switching loss is very low and the efficiency of system is high And the snubber condenser vised in a partial resonant circuit makes charging energy regenerated at input power source for resonant operation.<br/> The proposed conversion system is deemed the most suitable for high power applications where the power switching devices are used.<br/>
