ABSTRACT:
A detecting circuit is provided with at least one transformer, in which a first transformer is connected at its primary winding to an input power source and has two windings at its output portion to control the operation of two transistors respectively mounted in two switching portions in turn, the detecting resistor is coupled to the first transformer to detect a changing amount of current applied to a load, and a second transformer is provided with two input windings having a tap connected to the resistor and two output windings facing to the input windings, thereby outputting the signals isolated from the ground.
