A non-contact power supply system (100) according to one embodiment of the present disclosure is provided with: a power supply line (12) that supplies AC power in a non-contact manner to a power receiving device (120) provided in a moving body (130); and a plurality of power supply plates (10) that generate AC power and supply AC power to the power supply line (12). Each of the plurality of power supply boards (10) generates a control pulse that controls the generation of alternating current so that the timing of the center of an on pulse of the control pulse becomes the timing of the same cycle defined by a reference clock, and each of the plurality of power supply boards (10) changes the width of the on pulse. PWM control for controlling the alternating current supplied to the power supply line (12) is executed.
本公开的一个方式的非接触供电系统(100)包括以非接触的方式向移动体(130)所具备的受电装置(120)供给交流电的供电线(12)、和产生交流电并将交流电向供电线(12)供给的多个供电板(10),多个供电板(10)分别以使控制脉冲的导通脉冲的中央的定时成为由基准时钟规定的同一周期的定时的方式生成控制脉冲,该控制脉冲控制交流电的产生,并且多个供电板(10)分别通过使导通脉冲的宽度变化,执行控制向供电线(12)供给的交流电的PWM控制。
