Abstract

PURPOSE:To make the absolute value of a high voltage stable while always taking the balance of a load current by varying an oscillating frequency by a control voltage or current so as to correct the balance if the load current is unbalanced thereby controlling the oscillated control voltage to keep the high voltage within a prescribed value. CONSTITUTION:A single power source is employed for a power voltage supplied to a flyback transformer, oscillation circuits 3, 6 for driving switching circuits 2, 5 are provided and the oscillation circuits 3, 6 are operated independently of a synchronizing signal given to a multi-scanning type television receiver or the like. Moreover, a load current difference detection circuit 10 of high- voltage generating circuits 1, 4 and a circuit 11 for detecting a high voltage absolute error are provided and the frequency of the two oscillation circuits 3, 6 is controlled by a balance control circuit 12 at the same time to obtain a stable high voltage by a high-voltage stabilizing circuit and the current balance control and high-voltage control are applied. Thus, the variable power source for supplying to flyback transformer corresponding to the synchronizing signal is not required and a signal power source is used to make the absolute value of the high voltage stable while taking the balance of the load current.
