    Abstract: The locked phase active power current control circuit is composed of a DC source, an electronic switch, a driving transformer, a phase detecting unit, a current intercepting unit and a square wave controller. A DC signal provided by the DC source is converted into a square wave signal by the electronic switch for the driving transformer to operate a load. The electronic switch outputs the square wave signal to the phase detecting unit whereat a phase signal of the square wave is detected and the detected signal is transmitted to the current intercepting unit whereat the detected signal is compared with the current intercepted at the electronic switch, the driving transformer, or the load, and the comparison result is fed back to the square wave controller so as to set the operation frequency of the electronic switch. The essential principle of the present invention is based on the fact that the square wave is in phase with the first harmonic wave.
