  • In this paper new control strategy of series resonant converter system for power supply of communication station is suggested. Frequency controlled series resonant converter system is robust to load variations because it is POSR(Parallel Output Series Resonant: POSR) type. And it provides stable output voltage by changing switching frequency to input voltage variations. Firstly, operation analysis about suggested series resonant converter system was carried. Then simulations using ACSL(Advanced Continuous Simulation Langage) and experiments to actual system were carried to prove characteristics of suggested system.

  • In this paper, phase controlled series resonant converter (PCSRC) system for power supply of communication station is suggested. PCSRC system is robust to load variations because it is POSR (parallel output series resonant) type. And it provides stable output voltage by changing phase of MOSFET switches to input voltage variations. Firstly, operation analysis about suggested series resonant converter system was carried. Then simulations using PSIM and experiments to actual system were carried to prove characteristics of suggested system.

  • 본 논문에서는 통신 기지국용 전원으로 사용할 수 있는 주파수 제어 직렬 공진형 컨버터의 동작 원리 및 특성을 살펴보고 실제의 전원 시스템을 설계 및 제작하려고 한다. 주파수 제어 공진형 컨버터 시스템은 POSR(Parallel Output Series Resonant) 형태이기 때문에 부하에 강인하고 주파수를 제어함으로써 입력전압의 변화에도 안정된 출력을 보여준다. 실제 시스템 제작에 앞서 먼저 시뮬레이션을 통한 시스템의 분석을 하였고 시뮬레이션 프로그램은 ACSL(Advanced Continuous Simulation Language)을 사용하였다.

  • In this paper, phase controlled series resonant converter(PCSRC) system for control power supply in base station is suggested. PCSRC system is robust to load variations because it is POSR(parallel output series resonant) type. And it provides stable output voltage by changing phase angle of MOSFET switches to input voltage variations. Firstly, operation analysis about suggested series resonant converter system was carried. Then Computer simulations using PSIM were carried to prove characteristics of suggested system.
