Abstract

PURPOSE: To ensure the control of the output voltage by providing the control coil which is the orthogonal connection to the exciting coil and the oscillation coil and then giving the control to the control current flowing to said control coil.
CONSTITUTION: Exciting coil N1 and oscillation coil N2 are wound around transformer 10 and against the magnetic core having the saturation region along with feedback coil Nb wound. As transformer 10 is excited by exciting current I1, output voltage E0 is obtained at the parallel circuit of coil N2 and capacitor C. This voltage E0 is supplied to rectifying circuit 24, and the DC voltage is supplied to load RL. Then the fluctuation is detected by detection circuit 30 for the voltage to be supplied to load RL, and this detection output flows to coil Nc of transformer 10 in the form of control current Ic. With this current Ic and the magnetic flux produced by coil Nb, the working point of the magnetic core is controlled. And thus voltage E0 is controlled.
