Topology of a soft switching high frequency insulatied PWM DC-DC converter
고주파 절연형 소프트 스위칭 PWM DC-DC 컨버터의 토폴로지
Abstract
In this paper, proposed new partial resonance ZCS PWM controlled High frequency insulated Full-bridge DC-DC converter not using exciting current of high frequency transformer. It is compared with the existing principles in characteristics. It also realizes a widely stabilized ZVS operating using new ON-OFF control method at synchronized power rectification MOSFET of high frequency insulated transformer secondary. Besides, it is brought over 97[%] measurement efficiency by proposed DC-DC converter.
