Abstract

PURPOSE: To simplify the circuit constitution and at the same time realize a cost reduction, by incorporating the choke coil with the intermediate terminal and others.
CONSTITUTION: The choke coil 20 with the intermediate terminal is provided. The current flows through the coil 20 when the transistor TR1 is turned on, and the magnetic energy is stored (a) in the coil 20. And the stored energy is turned into the current flow F when the TR1 is turned off, thus holding the output voltage E at a constant voltage of -5V (b). In this instant, the potential at the observing point D jumps up to such level (positive potetial of value of winding ratio m of E×coil 7) as shown by D. In other words, the potential D becomes to +15V with m=3. On the other hand, the time factor during the ON state of TR1 is controlled so that an equal value may be secured between the upper and lower slant line area centering on the voltage E. Thus an extreme reduction can be avoided for the slant line areas even in such case the ratio between the input voltage and the output voltage is 10/1. As a result, the transformer or the diode can be eliminated in comparison with the conventional constitution, thus simplifying the circuit constitution.
