Abstract

This paper describes the load parallel type full-bridge high frequency resonant inverter can be used as power source. Output control method of proposed circuit is compared with pulse frequency modulation(PFM), pulse width modulation(PWM) and pulse phase variation(Phase-Shift). 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 according to the parameters such as switching frequency(${\mu}$), pulse width($\theta$d) the variation of phase angle($\phi$) by three driving signal patterns. Experimental results are presented to verify the theoretical analysis result. In future, Characteristics by three driving signal control method is provided as useful data in case of output control of a power supply in various fields as induction heating application, DC-DC converter etc.

본 논문은 고주파 전원에 사용되는 풀 브릿지 부하 병렬형 고주파 공진 인버터 회로를 연구대상으로 하고 출력제어기법으로는 펄스 주파수 변조(PFM, 펄스 폭 변조(PWM) 그리고 펄스 위상 변화(Phase-Shift)잎 경우를 비교 검토하였다. 회로의 해석은 정규화 파라메타를 도입하여 범용성 있게 기술하였고, 인버터 특성은 3가지 구동신호패턴에 의한 스위칭 주파수($\mu$), 펄스폭($\theta$d), Phase-Shift의 위상차각($\phi$)의 변화와 제 파라메타에 따라 특성 평가를 행하였다. 실험을 통해 이론해석의 타당성을 검증하였다. 향후, 3가지의 구동신호제어기법에 의한 특성들은 유도가열 응용, DC-DC 컨버터 등의 전원 시스템의 출력제어 시에 유용한 자료로 제공될 것으로 사료된다.
