Abstract

In modern society, various DC power supplies are required to operate the system circuits of various electric devices. A stable DC supply is essential for the normal operation of the circuit and the importance of the converter for this is very high. This study proposed a PWM DC-DC converter circuit that applied a 3-pole 2-zero voltage controller to a KY converter, a step-up DC-DC converter, to maintain a stable supply of output voltage regardless of load fluctuations. In order to prove the normal operation characteristics of the proposed converter circuit, a PSIM simulation and a circuit operation experiment on the PCB board were performed in comparison with the conventional converter circuit.

현대 사회에서 다양한 전기기기들의 시스템 회로를 동작시키기 위해서는 여러 직류 전원이 필요하다. 회로의 정상적인 동작을 위해 안정된 직류의 공급이 필수적으로 요구되고 이를 위한 컨버터의 중요성은 매우 크다고 할 수 있다. 본 연구는 부하 변동에 상관없이 출력전압의 안정적인 공급을 유지할 수 있도록 승압형 DC-DC 컨버터인 KY 컨버터에 3-극점 2-영점 전압 제어기를 적용한 PWM DC-DC 컨버터 회로를 제안하였다. 제안된 컨버터 회로의 정상 동작 특성을 입증하기 위해 기존의 컨버터 회로와 비교하여 PSIM 시뮬레이션 프로그램과 PCB 기판에서의 회로 동작 실험을 수행하였다.
