Abstract
PURPOSE:To reduce the load of an auxiliary power supply circuit and to minimize the size of the said power supply circuit, by applying the driving circuit power supply of the primary current interrupting element of a converter transformer after rectifying the secondary voltage of the converter transformer during steady working. CONSTITUTION:The voltage of an AC input 1 is rectified at 2 and applied via a switching element 4 of the primary winding 3a of a converter transformer 3. At the same time, the voltage of the input 1 is supplied to a driving circuit 7 of the element 4 as a power supply after the voltage reduction 13 and the rectification 14. Thus the element 4 is actuated to interrupt the primary winding current of the transformer 3. Then the voltage of the secondary winding 3b of the transformer 3 is supplied to a load 6 after the rectification at 5. The voltage of the winding 3b of such converter power supply device is rectified at 5 to obtain an output. This output is supplied to the circuit 7 via a reverse current preventing diode 17 as a power supply and along with the above-mentioned voltage reduction/rectification output (a).
