A regulator comprises a rectifying circuit that rectifies an alternating current output from an output terminal of each phase of the three-phase alternating-current generator 101 and passes a charging current to the battery B; first to third semiconductor devices T1, T2, T3 each of which has a first terminal x1 to which a control signal is input, a second terminal x2 connected to a negative side of the battery B, a third terminal x3 connected to a positive side of the battery B, and a fourth terminal x4 connected to an output terminal of a corresponding phase U, V, W of the three-phase alternating-current generator 101; and a controller CON that detects a charging voltage for the battery and outputs the control signals based on a detection result.
