Abstract

A power supply circuit for discharge type detecting circuits comprising a blocking oscillator (1) and a feedback circuit (2) for varying the oscillation period of the blocking oscillator. A detecting circuit acting as a load is connected to a secondary winding (L<u2>u) of a transformer (T) of the blocking oscillator (1). Base biasing for a transistor (T<ur1>u) of the blocking oscillator is controlled by the feedback circuit (2) to which is applied a negative voltage developed in a primary winding (L<u1>u) when the transistor (T<ur1>u) is cut off. As a result, since the oscillation period becomes shorter when the detecting circuit is in operation, power is rapidly supplied, whereas less power is supplied due to a longer oscillation period when the detecting circuit is standing by, whereby total power consumption is reduced.
