Power conversion device for solar cell.

摘要

A power conversion device of simple configuration for a solar cell which permits the solar cell (1) to be connected to the commercial power source (5) and enables the maximum electric power corresponding to the amount of incident sunlight to be drawn from the solar cell (1).

A power conversion device for a solar cell of this invention comprises a voltage controlled oscillator (3) capable of generating oscillation with a frequency which is the function of the dc output voltage (Ei) of said solar cell (1), an inverter (2) controlled based on the output frequency of said voltage controlled oscillator to receive the dc output current (Ji) of said solar cell (1) and convert said dc output current into an alternating current, and an inductor (4) serving to connect the ac output (EinV) from said inverter (2) to a commercial power source (5).
