本发明提供一种非接触式供电设备(1)之控制方法，其系激磁一次线圈(L1)，利用电磁感应现象而供电至设置于电子机器(E)的受电设备(10)之二次线圈(L2)。当在载置面(3)上有电子机器(E)时，一次线圈(L1)乃经由全桥接电路(43a)之全桥接动作而被激磁。当在载置面(3)上没有电子机器(E)时，一次线圈(L1)系经由全桥接电路(43a)之半桥接动作而被激磁。

The present invention provides a method for controlling a contactless power supply device 1 which supplies power to a secondary coil L2 disposed in a power receiving device 10 of an electrical apparatus E by utilizing an electromagnetic induction phenomenon by exciting a primary coil L1. When the electrical apparatus E is put on a loading surface 3, the primary coil L1 is excited by full-bridge action of a full-bridge circuit 43a. When the electrical apparatus E is not put on the loading surface 3, the primary coil L1 is excited by half-bridge action of the full-bridge circuit 43a.
