PURPOSE:To improve the efficiency of a device, and also to make it light, by alternately inverting an output of an electric power generating circuit. CONSTITUTION:A DC output from an electric power generating circuit 1 is supplied to a switching circuit 8, and is inverted alternately to plus and minus. That is to say, the switch is operated up and down by an output of an oscillator 7, and DC output voltage of the electric power generating circuit 1 is inverted alterately to the polarity of plus and minus. When the polarity of the switching circuit 8 is set to one side, the output voltage passes through as it is and is supplied to a load 6. On the other hand, when the polarity of the switching circuit 8 is reversed, the output voltage is applied to the load 6 in the opposite direction. When both the opertions are added, voltage of two times the output voltage of the electric power generating circuit 1 develops across the load 6. |
