ABSTRACT:
A feedback power control system includes: a multiplying unit receiving a work voltage corresponding to a voltage drop of an electrical component, and a feedback voltage corresponding to a work current flowing through the electrical component, and outputting a measuring voltage corresponding to a consumed power of the electrical component and having a value equal to a product of a value of the work voltage and a value of the feedback voltage; a control unit receiving the measuring voltage from the multiplying unit, and a reference voltage, and outputting a control voltage corresponding to a voltage difference between the measuring voltage and the reference voltage; and a regulating unit providing the feedback voltage to the multiplying unit, and including an amplifier that receives the feedback voltage from a series connection of transistor and a resistor coupled to the electrical component, and the control voltage from the control unit and that controls operation of the transistor.
