Abstract

PURPOSE:To realize a feedback circuit that works with high accuracy and without causing any oscillation nor unstable working, by providing a holding circuit that holds the output control quality, an adder that adds the contents of the holding circuit to the output of an amplifier plus specific switches. CONSTITUTION:A comparator 1 compares the target value Vi and the feedback quantity Vf and delivers the deviation between them. The control working signal, i.e. the output signal of the comparator 1 is amplified through an amplifier 2. Then the output control quantity Vo corresponding to the output signal of the amplifier 2 is coverted into the feedback quantity through a converter 3. A holding circuit 5 that holds the quantity Vo, an adder 4 that adds the contents of the circuit 5 to the output signal of the amplifier 2 plus switches 7 and 8 provided in series at the input and output sides of the circuit 5 respectively are provided to a feedback control circuit having such constitution as mentioned above. In addition, switch operating means 9 and 10 are provided to give the on/off drive to the switches 7 and 8 with a prescribed timing so that either one of the switches 7 and 8 is on while the other is off respectively.
