Abstract
In a power supply system, reducing influence of a noise etc., optimal electric power is supplied corresponding to power consumption of a receiving side load, and power consumption is decreased greatly. When a potential difference detectordetects that a power supply voltage of the receiving side load is decreased lower than a lower limit voltage threshold or increased higher than an upper limit voltage threshold, a burst interval setting unit sets up a burst signal of a pulse width corresponding to the detection result. A burst signal generator generates a burst signal based on the setup, and excites a control primary inductor. A burst signal detector generates a pulse signal in response to electromotive force of a control secondary inductor. A pulse width controller determines increase or decrease of the voltage value of the receiving side load from a no-signal period of a pulse signal, measured by a no-signal period measuring unit, and modifies and outputs a signal outputted by a alternating current generator so as to change a period or the number of times to excite a power primary inductor.
