Abstract

The invention relates to a forward converter comprising: a transformer (1) through which power is transferred from the primary circuit of the converter to the secondary circuit thereof, a control circuit (IC) for generating a first control signal and controlling the output voltage of the converter, a first switching means (S1) for interrupting the primary winding of the transformer (1) in response to the first control signal, an element (L) for storing energy, a second switching means (S2) synchronized with the first switching means (S1) in such a manner that the switches (S1, S2) are simultaneously in a conducting and, correspondingly, in a non-conducting state, a third switching means (S3) synchronized with the first switching means (S1) in such a manner that the switches (S1, S3) are alternately in a conducting and, correspondingly, in a non-conducting state. To provide simple control, the converter comprises converter means (2, 3, 4) for controlling the second (S2) and the third (S3) switching means responsive to the first control signal generated by the control circuit (IC), whereby the power required for controlling the switching means (S2, S3) is derived from the first control signal generated by the control circuit (IC).
