Abstract
PURPOSE:To improve the power supply efficiency by connecting the collector of an input transistor(TR) of a push-pull circuit of Darlington connection to a tap provided to the primary winding of a power transmission transformer. CONSTITUTION:TRs 1, 2 are connected in push-pull to the primary winding of the power transmission transformer T and the 3rd TRs 3, 4 are connected in Darlington to the base of the TRs 1, 2. The collector of the TRs 3, 4 is connected to the taps 7, 8 via resistors R1 and R2 respectively provided to the primary winding of the transformer, and a capacitor C1 is connected between the tap 2 of the primary winding and the connecting point of the emitters of the TRs 1, 2 and a power voltage Vcc is connected to the tap 2. Thus, the TRs are switched completely to avoid power consumption in the TRs thereby improving the circuit efficiency.
