Abstract
PURPOSE:To ensure an apparatus action by providing an overcurrent protection means with a proportional element and an integral element. CONSTITUTION:A switching regulator is composed of a transformer T1, a switching means Q1, a rectifier diode D1, a flywheel diode D2, a smoothing circuit S, a constant-voltage control means R, an overcurrent protection means P and others to ON-OFF control a switching means Q1 to supply a certain output voltage. In this case, the overcurrent protection means P is equipped with a switching means, a current detection means M, and a comparison means CO; and is provided with a proportional element by a resistance R2, and an integral element of a parallel circuit of a resistance R3 and a capacitor C3. Thus, when the overcurrent of said switching means Q1 ends in a short period, said overcurrent protection means P does not operate so far as said overcurrent is not very large, while said protection means P operates surely with a little delay of time when the overcurrent continues for a long period.
