Abstract

This paper presents the high frequency resonant inverter of class D SEPP(Single-Ended Push Pull) type using LS-ZVS-LSTC, which can reduce the switching losses during the turn-on and turn-off switching time. The analysis of high frequency resonant inverter using LS-ZVS-LSTC(Low-loss Turn-off Snubber Capacitor) proposed in this paper is described in general by adopting the normalized parameters. The operating characteristics of the proposed high frequency resonant inverter were also evaluated by using the control parameters such as the normalized control frequency(μ), the normalized load time constant(τ), the coupling factor(κ) and so on. Based on the characteristic values through the characteristics of evaluation, an example of the design method of the 1.8[kW] class D SEPP type high frequency inverter is suggested, and the validity of the theoretical analysis is verified using the experimental data.

본 논문에서는 스위칭 시 발생하는 턴-온 및 턴-오프 손실을 줄일 수 있는 LS-ZVS-LSTC를 이용한 D급 SEPP형 고주파 공진 인버터에 대해서 나타내고 있다. 본 논문에서 제안한 LS-ZVS-LSTC를 이용한 고주파 공진 회로의 해석은 무차원화 파라메타를 도입하여 범용성 있게 기술하였다. 또한 제안 인버터의 운전 특성은 무파원화 제어 주파수(μ), 무차원화 부하시정수(τ), 결합계수(κ) 등의 제어 파라메타를 이용하여 특성 평가를 수행하였다. 특성 평가를 통한 특성치를 토대로 1.8[kW] D급 SEPP형 LS-ZVS-LSTC 고주파 인버터 설계 기법의 일예를 제시하였으며, 이론 해석의 정당성은 실험을 통해 입증하였다.
