Patent number: 9285410Abstract: A control circuit 1 for determining a phase sequence of a power generator includes a frequency control unit, a cycle obtaining unit, a determination unit, and an output-supply control unit. The frequency control unit controls a frequency of a sensor signal synchronous with an operation of the power generator, and the cycle obtaining unit obtains a cycle of the sensor signal whose frequency is controlled by the frequency control unit. The determination unit determines the phase sequence of the power generator by detecting timing at which an output voltage outputted from each of the phases of the power generator has risen using the cycle of the sensor signal obtained by the cycle obtaining unit. The output-supply control unit controls a drive circuit according to the phase sequence of the power generator determined by the determination unit.Type: GrantFiled: December 25, 2012Date of Patent: March 15, 2016Assignee: SHINDENGEN ELECTRIC MANUFACTURING CO., LTD.Inventors: Yuta Inoguchi, Takeaki Sugimoto
