<p>PURPOSE:To supply good quality power for the first load with constant voltage and constant frequency and also supply good quality power for the second load with variable frequency and constant voltage. CONSTITUTION:In a constant frequency power supply equipment comprising an AC generator 10 driven by an engine, a converter 4 made of a rectifier circuit 5 and an inverter 6 and generator control means 8, more than 2 pairs of polyphase output windings 3A and 3B are equipped as the output windings of the AC generator 10, one pair of the output windings 3A are connected to the input of the converter 4 for obtaining AC power PA of constant voltage and constant frequency for the first load from the converter 4, and the output windings 3B of the remaining pair is used for other load such as the second load. Output from this output winding 3B is applied to the generator control means 8 for controlling the field input of the AC generator 10, and the supply power PB to the second load is arranged to a required power being different from the power PA for the first load.</p> |
