Abstract

PURPOSE: To prevent a transformer from partial excitation by varying time widths of base driving pulse signals alternately in response to the storage time of each of a pair of switching transistors which repeat ON-OFF alternately.
CONSTITUTION: When a transformer T is excited partially, collector currents ic1 and ic2 of transistors TR1 and TR2 are detected by collector current detectors DET1 and DET2 and converted into DC voltages e1 and e2. By comparing these two detected voltages e1 and e2 through a differential amplifier DEF the driving pulse width is controlled so that the current applied to a pair of switching transistors TR1 and TR2 may be equal.
