Abstract

In this paper, a design method of LCL filter at the AC input side of a voltage source PWM converter is proposed. Effective method to prevent pollution of the utility caused by high frequency current ripple is to use a AC input LCL filter, The C elements in the filter provide a low impedance path for the high frequency component, preventing them from entering the utility. The resistors In series with the capacitors are used for damping the resonance in the filter The design examples are shown and the validity of the proposed design method is verified through the PSIM simulation.

본 논문에서는 전압형 PWM 컨버터의 교류 입력측 LCL 필터의 설계기법을 제안한다 기존의 전압형 PWM 컨버터에서 전원계통으로 흘러 들어가는 스위칭 고조파전류를 억제하기 위해 교류 입력측에 LCL 필터를 설치하는 것은 매우 경제적이고 효과적인 방법이다 필터 커패시터로 스위칭 고조파전류를 흡수하며 공진을 억제하기 위해 수동 댐핑 저항을 이용한다 UPS용의 LCL 필터 구조 PWM 컨버터의 설계예시를 보였으며 제안한 설계기법의 타당성을 입증하기 위해 PSIM을 이용한 시뮬레이션을 행하였다.
