ABSTRACT:
A pulse absorbing circuit is disclosed for a power source circuit for absorbing an abnormal pulse when an input current at a primary winding of an output transformer in a switching power source is cut off. The pulse absorbing circuit includes a capacitor, one end of which is connected to a secondary winding output terminal of a transformer in a phase opposite to a primary winding input terminal thereof. A first rectifying element is provided, an anode of which is connected to the other end of the capacitor and a cathode of which is connected to an output terminal of a rectifying circuit arranged at a secondary winding side of the transformer. A second rectifying element is provided, a cathode of which is connected to a junction between the first rectifying element and the capacitor. A conductor is inserted between a ground terminal and the second rectifying element. The conductor has, for example, a coil for absorbing and effectively reutilizing abnormal pulse energy.
