Abstract
PURPOSE:To eliminate the trouble of detection of an effectively value of a non-sine wave to control the phase in a wide range with a simple circuit constitution, by not detecting a load voltage but detecting a power source voltage to control the phase of the load power. CONSTITUTION:A power source voltage detecting circuit 15 consists of a full- wave rectifying circuit consisting of a diode D1 and an operational amplifier OP1, a peak hold circuit consisting of an operational amplifier OP2, a diode D2, and a transistor Trr for reset, and an A/D converter AD, and the operational amplifier OP1 compensates the forward voltage drop of the diode D1. An output voltage Vo of the full-wave rectifying circuit is applied to the peak hold circuit, and its peak voltage is changed in a capacitor C.
