Abstract

PURPOSE: To control precisely power with simple constitution by controlling power, consumed in a load, in constant or according to a desired program.
CONSTITUTION: Electric power to be supplied to a load 7 is controlled by controlling an output of a rectifying circuit 1 with a saries control circuit 2. Voltage and a current signal of the load 7 is applied to an anglog operating circuit 5 to multiply through an isolation amplifier 6, and the output of the operation circuit 5 and the signal of power setting and change over circuit are supplied to a comparator 3 through a gain controller 4. The output of the comparator controls the series control circuit 2 to control the power to be supplied to the load 7. When the power to be supplied to the load is controlled according to a desired program, the output of a sequence controller 8 is supplied to the gain controller 4 through the power setting and change over circuit 9
