Abstract
A switching power transmission device includes a transformer having primary and secondary windings, and two driving windings, the transformer being connected with an inductance and a capacitor. First and second switch circuits are connected to input power and the transformer so as to switch the current flow in the primary winding to produce a switched output on the secondary winding. A current, flowing through the first switching device, is detected by a current detecting device to control the current flow based on the detected value of the current.
