Abstract
Provided is a control circuit capable of efficiently supplying electric power from an alternating-current generator to a load, and a power generation device having this control circuit. A control circuitfor controlling electric power to be supplied from a power generatorto a batteryis provided with: a rate-of-change obtaining unitconfigured to obtain a rate of change of a sensor cycle for a sensor signal synchronous with an operation of the power generator; an estimation unitconfigured to estimate a next sensor cycle using the rate of change of the sensor cycle obtained by the rate-of-change obtaining unit; and an output-supply control unitconfigured to perform PWM control of switching elements provided for a drive circuitusing the next sensor cycle estimated by the estimation unit
