Abstract

The 4kW class inverter for portable ESS designed through this study achieves lightweight and high power density by reducing the volume of passive devices (capacitors, inductors, etc.) suitable for portable use, and minimizes heat loss of the MOSFET through the low on resistance of the MOSFET. So that high efficiency can be achieved. In addition, in order to deliver high quality energy, it is designed to have a low THDV in accordance with the current KEPCO business handling guidelines, and is designed to output a sine wave with low distortion.

본 연구를 통해 설계된 Portable ESS를 위한 4kW급 인버터는 휴대용에 걸맞게 수동소자(캐패시터, 인덕터 등)의 부피를 줄여 경량화 및 높은 전력밀도를 달성하고, MOSFET의 낮은 온저항을 통해 MOSFET의 열손실을 최소화하여 높은 효율을 달성할 수 있도록 했다. 또한, 높은 품질의 에너지 전달을 위해 현행 한전 영업업무처리지침기준에 따라 낮은 THDV를 가지도록 설계되어 왜곡이 낮은 정현파가 출력되도록 설계되었다.
