ABSTRACT:
A system linking apparatus for generated electric power which may be made smaller and more efficient. The system linking apparatus is intended for connecting an electric power system to an output of a power generator through a linking inverter (PWM inverter). The system linking apparatus includes a magnetic energy regenerating circuit, a diode rectifier, and a capacitor. The magnetic energy regenerating circuit has a capacitor for condensing magnetic energy condensed in the power generator. The diode rectifier is connected with the magnetic energy regenerating circuit and operates to dc convert electric power generated by the power generator and output the converted power to the linking inverter. The capacitor is connected with the diode rectifier and operates to keep a dc output to the linking inverter at a predetermined voltage.
