Abstract

PURPOSE:To obtain plural metastable outputs by magnetically coupling the secondary windings of a converting transformer having plural secondary windings by an auxiliary transformer wherein a dummy load is connected to the output terminal of any secondary winding and feedback is done through a control circuit. CONSTITUTION:With a switching element 1 repeated on and off and the DC voltage V supplied to the primary winding T1 of a converting transformer T interrupted, the voltage responds to the ratio of transformation is induced at three secondary windings TM1, TM2 and TN during on period. The voltage induced at three secondary windings charges each capacitor, C1, C2 and C3 through each rectifier diode D1, D2 and D3, and is stored in each coil, L1, L2 and L3 during on period. The energy in each coil, L1, L2 and L3 charges each capacitor, C1, C2 and C3 through each rectifier diodes, D1', D2' and D3' during off period and the smoothed DC voltage is sent to output terminals, 21, 22 and 23. A dummy load 4 is connected to the output terminal 23 and the output is fed back by a control circuit 3.
