Abstract

PURPOSE:To save power consumption while performing high-speed operation, by connecting a series circuit of a diode and a switch between the base and collector of a switching transistor and turning on this switch at the end of conduction period of the transistor. CONSTITUTION:When a switching element SW6 repeats on/off at the period T, a transistor TR1 turns on at on-period t1. When a switching element SW5 is temporarily turned on at the latter half of the period t1, since the collector of the TR1 is clamped, the TR1 is unsaturated and transisted from the conduction to the nonconduction quickly. The on-time of the SW5 is short and the power consumption can be saved.
