Abstract

PURPOSE: To stabilize operation by suppressing fluctuations of an output voltage by providing a delay element to a signal system controlling one or a few switching elements.
CONSTITUTION: A separately-excited switching control power circuit is composed of transistor Q, choke coil L, error amplifier AMP1, capacitor C, comparator COM, diode D, triangular wave oscillator TG, etc.; a constant voltage is applied from reference voltage source Es to one input terminal of amplifier AMP1, and a fedback output voltage to the other input terminal. The output of amplifier AMP1 is further applied to one input terminal of comparator COM, and the output of generator TG to the other input terminal. A signal controlling transistor Q is delayed by connecting resistance R and capacitor C to the feedback circuit of amplifier AMP1 of the power circuit so as to make the amplitude of the output voltage of amplifier AMP1 less than the output amplitude of generator TG, and consequently transistor Q is stably controlled to stabilize output voltage E0.
