Abstract
Grid voltage variation is usually happened but existing PV inverter dose not consider this variation before inverting into AC power. This inverting is a cause of unnecessary losses. This paper proposes that DC-link should be changed for removing those losses. Furthermore, maximum efficiency tracking control algorithm with variable DC-link voltage is proposed and verified by simulation and experiment.
