Abstract
PURPOSE: To eliminate power consumption in a waiting state under power failure, by providing a transistor whose emitter is connected to a feedback winding terminal of a transformer and whose collector is connected to the base of an oscillation transistor.
CONSTITUTION: A load 13 is connected to a DC-DC converter A and a constant voltage circuit 20 coupled to an AC power source so that the load is driven by the converter or the constant voltage circuit. In the converter A, an oscillation transistor 1 is driven by the current of a battery 3 through a transformer 2 and a transistor 17 to perform blocking oscillation to supply a DC voltage to the load 13. The base of the transistor 17 is controlled by the output voltage through another transistor 10 to stabilize the voltage. As a result, in a waiting state under power failure, no current flows from the battery 3 to the transistor 10, power consumption is elminated and a fly-back voltage is raised to heighten an efficiency.
