PROBLEM TO BE SOLVED: To provide a photovoltaic power generating inverter capable of eliminating the need for a booster circuit. SOLUTION: This photovoltaic power generating inverter is provided with a solar cell voltage detecting means 3, which detects voltage of a solar cell 1 and a system voltage detecting means 10 which detects voltage of a system power supply 11, and is constituted of a switch for flowing current from the solar cell 1 through the system via an inductance 9 and a control means for controlling the switch, for flowing the current through the system power supply via the inductance 9, only when the voltage of the solar cell is larger than that of the detected system power supply. The switch is thereby controlled to make the current flow through the system power supply via the inductance, only when the voltage of the solar cell 1 is larger than that of the system power supply 11, thus attaining feeding of power into the system without the need for a boosting means. |
