| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | n recent years, research and development on a low voltage\,/\,high current output-type DC--DC converter have been attracting special interests in telecommunication and information power supplies as well as automotive electric power systems. For reducing switching losses and EMI levels in those electric power applications, several soft switching DC--DC converter topologies have been discussed with their control schemes. In this study, a novel high-frequcny transformer linked ZCS-PWM DC--DC converter that is constructed with an asymmetrical auxiliary resonant snubber-assisted half-bridge inverter and a current doubler rectifier is proposed. By investigating the operation and characteristics of this DC--DC converter, the ZCS scheme with the auxiliary snubber is verified to be effective, and design considerations of the resonant circuit parameters including the high- frequency transformer is described in this paper. | |
