A power regulator, power control system and the method thereof are provided. A detecting device receives a feedback signal from a resistive load device, and outputs a control signal, which could be a voltage or a current. While receiving the control signal, the power regulator outputs a drive voltage in a proportional way. In the proportional way, full power drive voltage is outputted in a continuous output time period and is stopped outputting in a continuous non-output time period. The resistive load device receives the drive voltage and then outputs the feedback signal to the detecting device. Similarly, in the proportional way, the full power drive voltage is outputted in the continuous output time period and is stopped outputting in the continuous non-output time period. Thus, it is able to decrease the amount of harmonic waves. |
