Abstract

PURPOSE:To suppress the irregular energization of a transformer by providing a pair of switching elements and providing different control signals applied to the respective elements by a predetermined value. CONSTITUTION:A pair of switching transistors Q1, Q2 and a control circuit for controlling the transistors as designated by Xc is provided. A pulse width control signal depending upon the voltage between the output voltage detecting terminals S and S' is applied to the transistor Q1, a drive signal delayed by 180 deg. from the pulse width control signal applied to the transistor Q1 is applied to the other transistor Q2 so as to equalize the conducting duration of the transistors Q1, Q2 in one cycle. Since the irregular energization of the transformer can be sufficiently suppressed and the conducting duration of a pair of the switching elements is equal in this manner, it is pulse width controlled with one cycle delay without irregular energization, and can accelerate the control response.
