<p>Provided are a control circuit capable of determining the phase sequence of a multiphase alternating-current power generator, and a power generation device provided with the control circuit. A control circuit (1) for determining the phase sequence of a power generator (5) is provided with a frequency control unit (11), a period acquisition unit (12), a determination unit (13), and an output supply control unit (14). The frequency control unit (11) controls the frequency of a sensor signal that is synchronized with the operation of the power generator (5), and the period acquisition unit (12) calculates the period of the sensor signal, the frequency of which is controlled by the frequency control unit (11). The determination unit (13) detects the rising timing of the output voltage outputted from each phase of the power generator (5) using the period of the sensor signal calculated by the period acquisition unit (12), and determines the phase sequence of the power generator (5). The output supply control unit (14) controls a drive circuit (30) in accordance with the phase sequence of the power generator (5) determined by the determination unit (13).</p> |
