ABSTRACT:
A multilayer-winding fly-back transformer is provided with first, second, third, fourth, fifth and outermost cylindrical bobbins made of dielectric material and arranged concentrically. A magnetic core is inserted in the first or innermost bobbin, and a primary winding is wound in layers on the outer periphery of this bobbin. The first, second, third and fourth secondary windings are wound in layers round the second, third, fourth and fifth bobbins, respectively. First, second, third and fourth diodes are connected between the first and second secondary windings, the second and third secondary windings, the third and fourth secondary windings, and between the fourth secondary winding and an output terminal, respectively. A capacitor is formed between the cathode of the fourth diode and the anode of the third diode.
