Abstract

PURPOSE: To suppress sustained oscillation which takes place on the side of a power source due to negative conductance which is caused on the inpout to a chopper, by equivalently cancelling the negative conductance.
CONSTITUTION: The input voltage to a chopper A, namely, the voltage Vs of a power source is applied to an adder E through a DC component blocking filter C of bypass type, band pass type or the like and an amplifier D. A first set current Ir and a second set current, which is supplied from the amplifier D, are added to each other by the adder E. The added current is applied to a comparator B. The chopper A is controlled by the output of the comparator B to cancel negative conductance which is caused on the input to the chopper.
