Zusammenfassung:	PURPOSE: To control the output voltage from a DC voltage blocking converter accurately with small loss without requiring any secondary control of a controller by inserting a second coil coupled with a first coil into a demagnetization circuit. CONSTITUTION: A demagnetization circuit A is connected with a second coil L2, a third diode D3 and a second capacitor C2 to form a 'parasitic blocking converter circuit'. This circuit induces charging of the second capacitor C2 and a voltage is formed in a first resistor R1 connected in parallel. Consequently, a current flows through a series circuit of the first and second resistors and a voltage compensating for the fluctuation is applied to the input side of a controller which is not controlled on the secondary. According to the arrangement, a control loop for bridging the potential can be eliminated as a whole.
