Abstract
A system for controlling power supply according to the present disclosure includes a controlled device, a waveform control circuitry and a power detection and control circuitry. A supply voltage is provided to the controlled device for supplying power and, at the same time is applied to the waveform control circuitry for changing its waveform so as to generate a control signal. The control signal is then received and analyzed by the power detection and control circuitry to output a control command, which is used to control the controlled device. Based on the system for controlling power supply, there is also provided a method for controlling power supply, which may be implemented by a smart dimming system to realize remote control of lighting-on, lighting-off, dimming and color temperature regulation.
