ABSTRACT:
There is provided a resonant circuit incorporating at least a coil L1 therein and a switching circuit for oscillation is connected to the resonant circuit and voltage doubler rectifier circuits 31 and 32 including capacitors C11, C12, C21 and C22 and diodes D11, D12, D21 and D22 are also connected to the resonant circuit. When the switching circuit for oscillation is turned on and off, the resonant voltage V.sub.L1 is generated in the resonant circuit and rectified with a voltage doubler amplitude by the voltage doubler rectifier circuits 31 and 32. A switching circuit for output changing over is connected to zero voltage terminals of the diodes D11 and D21 in the voltage doubler rectifier circuits 31 and 32. When the switching circuit for output changing over is turned on and off, an output voltage is selectively generated at output terminals OUT1 and OUT2.
