Abstract

Small-scale photovoltaic (PV) inverter can be widely used in households and many other occasions. This paper uses IR digital controller IRMCF143 to design an 800W single phase PV inverter. This chip integrates two processors especially for inverter control. A two-stage topology is applied in the system. Both stand-alone and grid-connected control strategies are analyzed. Combine the system requirements and the chip characteristics, the system hardware framework, maximum power point tracking (MPPT) algorithm, islanding detection methods and fault handling functions was designed. At last, the experimental system is built. The two processors integrated in one chip can work independently but cooperatively. The aim to cut the design cycle and cost is realized and the PV inverter system is tested to achieve the design target and get a stable running.
