Characteristic Analysis of SEPP Type D-Class High Frequency Resonant Inverter using ZVS

ZVS를 이용한 SEPP형 D급 고주파 공진 인버터의 특성해석

This paper was described about principle and form of proposed circuit made use of soft switching technology ZVS(Zero Voltages Switching) and ZCS(Zero Current Switching) to reduce turn on and off loss at switching. Also, the analysis of the proposed circuit is described generally by using normalized parameter and basic operating principle and driving characteristics have been evaluated as to switching frequency and load p arameter. Based on the characteristics value, a method of circuit design is proposed. In addition, Pspice's simulation and experimental waveforms are compared with theoretical ones. The experimental results shows that the proposed Inverter can be used practically such as power source system for induction cooker etc.
