ZVS를 이용한 공진전류 주입형 고주파 공진 인버터의 특성해석

Characteristic analysis of the resonant current injection type high frequency resonant inverter using ZVS

A half-bridge type resonant current injection type high frequency resonant inverter using ZVS(Zero-Voltage-Switching) used as power source of induction heating at high frequency is presented in this paper. This proposed inverter can reduce distribution of the switching current because of using the current of serial resonant circuit to the input current of the parallel one. The analysis of the proposed circuit is generally described by using the normalized parameters, the principle of basic operating and the its characteristics are estimated by the parameters such as switching frequency and load resistance. According to the calculated characteristics value, this paper proves the validity of theoretical analysis through the Pspice.
