Abstract

This paper is elaborates on the pure sine wave single phase inverter of 500W level which is driven by battery. The inverter is structured to raise the battery voltage to 400V by using the push-pull topology, and by using H-bridge with the high voltage, it outputs common 220VAC. This topology is utilized to use the power semiconductor device in order to design and manufacture the inverter of 500W at input voltage rating of 12VDC. As a result, the efficiency exceeds 90% in partial sections, but on average, the efficiency is approximately 89.5%, and as for output voltage, frequency fluctuation range and THD, the result can be less than ${\pm}5%$.

논문은 배터리로 구동되는 500W급의 순수사인파 단상인버터에 관한 연구이다. 푸쉬풀 토폴로지를 이용하여 배터리의 전압을 400V로 승압하고, 이 승압된 전압을 H-브리지를 이용하여 상용 220VAC를 출력하는 인버터 구조이다. 이러한 토폴로지를 이용하여 정격입력전압 12VDC에 500W의 인버터를 설계 제작하였다. 그 결과 효율은 일부구간에서 90%를 넘었으나 평균적으로는 약 89.5% 정도의 효율을 나타내고, 출력전압, 주파수 변동 오차 및 THD는 ${\pm}5%$ 미만의 결과를 얻을 수 있었다.
