PHOTOVOLTAIC POWER GENERATION SYSTEM UTILIZING COMMERCIAL SYSTEM POWER SUPPLY

摘要

A photovoltaic power generation system (100) comprises a solar cell module (1A), a step up/down circuit (2A) for regulating the voltage level of DC power generated from the solar cell module (1A), a rectifier circuit (5) for converting the AC power from a commercial system power supply (6) into a DC power, and an inverter (3) for producing an AC power to be supplied to a load (7A) from the DC power having a voltage level regulated by the step up/down circuit (2A) and the DC power converted by the rectifier circuit (5).
