Abstract: Buck-boost type or buck type chopper circuits and transistors are employed as inverters (IV1, IV2) and power synchronizing switches (SW1, SW2), respectively. A PWM signal is applied to transistors of the chopper circuits to convert DC voltage generated by solar cells (DC1, DC2) into positive and negative half-wave AC voltages for an AC power supply (AC1). The inverters (IV1, IV2) output the AC voltages from their AC output terminals on alternate half cycles thereby to cause backflow of power. The power synchronizing switches (SW1, SW2) performs not only the function of transmitting the half-wave AC voltages generated by the inverters (IV1, IV2) to the AC power supply (AC1) in accordance with the AC cycle of the AC power supply (AC1), but also the function of, when one of the inverters is in operation, insulating the other from the AC power supply (AC1).
