PURPOSE:To form one time output voltage and twice output voltage from one output winding of a switching transformer by connecting a single-phase full-wave double voltage rectifier with the secondary side winding of the transformer. CONSTITUTION:A transformer 2 is connected with the output side of an inverter 1. A single-phase full-wave double voltage rectifier having diodes 4, 5, 7, 8, chokes 6, 9 and capacitors 10, 11 is connected with the secondary side winding 3 of the transformer 2. When the negative terminal of the capacitor 11 is grounded, a voltage 2E is produced from the positive terminal of the capacitor 10, and a voltage E is produced from the positive terminal of the capacitor 11. When the negative terminal of the capacitor 10 is grounded, a voltage E is produced from the positive terminal of the capacitor 10, and a voltage-E is produced from the negative terminal of the capacitor 11.
