PURPOSE:To enhance the constant voltage accuracy by connecting an inductance element having an inductance of simple attenuating characteristic to a DC current and a capacitance element between the secondary winding of a transformer and a rectifier. CONSTITUTION:A switching element is connected in series with the primary winding 1a of a transformer 1, and is controlled ON or OFF by a control circuit 3 which receives the output of a control winding 1c. A parallel circuit of inductance elements 11, 11' and capacitance elements 12, 12' are connected between the secondary windings 1b, 1b' of the transformer 1 and rectifiers 9, 9'. The elements 11, 11' has simply attenuating characteristic to the DC current in the inductance of high frequency by the DC magnetomotive force higher than 1.0AT. |
