Abstract
PURPOSE: To eliminate a wasteful generation of heat, by means of controlling a base current of the transistor in the oscillating circuit in accordance with a level of the load, to provide an operational condition with its efficiency always near the highest.
CONSTITUTION: If closed a switch 10, a current is supplied to the base of a transistor 1 and 2 through a resistor 11 from a DC power source 9, with an oscillation started. And during the period until a regular output voltage is reached, a variable resistance element 18 is being held at a minimum value by an output signal of voltage detector 17. In a short time, with a regular output voltage given, the variable resistance element 18 will be controlled at an optimum level in accordance with a level of the load. If the load increases, the output voltage slightly goes down, causing its detected signal to lessen the variable resistance element 18, resulting in an increase of the base current for the transistor 1 and 2, and an action will work to return the output voltage to the former level with a stabilization restored to at the optimum value.
