Pulse type activating system for power supply, composed of a boosting circuit, a pulse width modulating (PWM) circuit, a sine-wave generating circuit, an MOSFET output circuit, an analog-to-digital converting circuit (ADC), a temperature sensing circuit, an overload detecting circuit, a short circuit detecting circuit, a warning circuit and a CPU. The CPU collectively controls the above circuits and in the instant of activation of the load, the CPU provides intermittent high voltage for shortening the activation time of the load. The CPU also provides protection effect for the load.
