PURPOSE:To operate many loads with a small power source voltage by connecting a power source with the primary winding of a transformer, connecting a load with the secondary winding to supply a current to the load, and supplying power to another load by utilizing a counterelectromotive force generated in the primary winding. CONSTITUTION:A power source E is connected with the primary winding L1 side of a transformer T1 of a booster 1, and the first load circuit 2 is connected with the secondary winding L2 of the transformer T1. The booster 1 has a transistor Q1, and oscillated by positively feeding back by the sub winding L2 of the transformer T1. When the transistor Q1 is OFF, a raised counterelectromotive force is generated in the winding L1. Thus, after it is stored in a capacitor C8, it is then smoothed and supplied to the second load circuit 3.
