摘要
A suitable single-phase inverter for the utility connected residential photovoltaic generation system is proposed. The proposed single-phase PWM current source inverter (CSI) has an additional branch to the normal single-phase bridge circuit. The auxiliary switches avail to adopt the composite PWM control, and a double frequency parallel resonance circuit (LC tank circuit) is inserted in the DC side of the inverter in order to reduce the size and weight of the DC reactor. The smooth DC current without pulsation is supplied from PV array, and the inverter provides a sinusoidal AC current for domestic loads and the utility line. In the system, the PV array can pray an important role as a current-limiter by its V-I characteristics.
