Abstract (in Japanese) (See Japanese page) 
(in English) A quasi-resonant converter which uses flyback topology can realize soft switching with relatively simple circuit. However, a switching device with high breakdown voltage is necessary to achieve complete zero voltage switching when the input voltage is high and it causes decrease of efficiency because a switching device with high breakdown voltage has relatively high on voltage. Therefore, we analyzed efficiency and noise of a quasi-resonant converter with a low breakdown voltage and low on voltage switching device under the condition of non-zero voltage switching. As the result of the analysis, good characteristics are achieved with non-zero voltage switching.
