1. A power converting apparatus comprisinga solar array provided with maximum power operating point tracking control;
- DC-AC inverting means for converting a DC output voltage from the solar array into AC having a controlled voltage and frequency, and supplies an output thereof to a load;
a commercial power source which compensates an insufficient power when a generated power of the solar array is less than the consumed power of the load;
rectifying means which converts an AC voltage supplied by the commercial power source into a DC output and supplies that output to said DC-AC inverting means; and
regenerating means which regenerates a surplus power into the commercial power source when the generated power of the solar array exceeds the consumed power of the load.

Abstract
A power converting apparatus comprising intermediate DC power which rectifies AC from a commercial power to output DC, a solar array connected in parallel to the intermediate DC power, an inverter which converts DC inputted respectively from the intermediate DC power and the solar array into AC having the variable frequency and the variable voltage, then supply its AC output to a load, and circuit networks for power regeneration which regenerates a surplus power of the solar array into the commercial power, when the generated voltage of the solar array exceeds the prescribed voltage.
