Claims

[Claims for Utility Model Registration] A phase shift control device that constantly obtains a sine wave voltage whose phase is shifted by 90 degrees through a phase shift controller,
a first square wave conversion circuit that outputs a square wave with rising and falling points at the 7-point cross point of the sine wave input voltage phase-shifted by the phase shift controller; , a second square wave conversion circuit that outputs a square wave whose rise and fall points are at the zero loss point of the sine wave input voltage; and input the outputs of the first and second square wave conversion circuits. and an integrator circuit that integrates the output of the discriminator circuit, and the output signal of the discriminator circuit is sent to the phase shift controller via the integrator circuit. A phase shift control device characterized in that a feedback signal is inputted as a control signal, thereby obtaining a sine wave output voltage that is normally phase shifted by 90 degrees from the phase shift controller.
