PURPOSE: To miniaturize a power unit by connecting a specified capacitor in series to the specified number of capacitors which are connected in series when current flows through a rectifier circuit and connecting it in parallel to the specified number of the capacitors which are connected in series when current does not flow. CONSTITUTION: Voltage stabilized by first and second constant voltage diodes 7 and 8 is supplied to first and second loads 10 and 11. Voltage decided by a constant voltage circuit 9 is supplied to a third load 12. Then, respective loads stably operate. The increase of current can be accumulated in a third capacitor 6 and a fourth capacitor 13 for the voltage boost of a commercial AC power source 1 by non-stabilizing either one of the plural serial power sources constituted of first, second and third capacitors 4-6 connected in series. The voltage drop required for generating DC power from the power source 1 can be reduced and loss power can be reduced by the first constant voltage diode 7 and the second constant voltage diode 8. |
