공진형 고주파 인버터에서의 공진주파수 추적을 위한 PLL 기법
PLL Technique for Resonant Frequency Trancking in High Frequency Resonant Inverters
초록
The PLL(Phase-Locked Loop) techniques re employed to make the switching frequency of a resonant inverter follow the resonant frequency which may vary due to the load variations during operation. The conventional design guide of PLL is not suitable in these case since the inverter characteristics are not considered. In this paper the phase characteristics of a resonant inverter is analysed and added to the closed loop. And the design of PLL with digital phase detector is illustrated for the output frequency to track the resonant frequency of the inverter.
