ABSTRACT:
A switching type power supply circuit having a series connection of a switching element and an inductance element connected between output terminals of a DC voltage source, a series connection of a fly-wheel diode and a detecting resistor connected between the junction of the switching element and inductance element and the ground, and a capacitor connected between the junction of the inductance element and the DC voltage source and the ground, in which when a voltage across the detecting resistor exceeds a predetermined level, the supply of the switching pulse to the switching element is stopped to render the switching element OFF.
