Abstract

The converter comprises an electronic switching device (SCR1) coupled in series with the primary winding (N1) of a transformer (M) across a rectified AC supply for producing in the primary winding (N1) a primary current pulsating at a desired frequency. Coupled across a secondary winding (N2) of the transformer (M) is a rectifier (D3) and capacitor (C2) arranged, by selection of the value of the capacitor (C2), as a tuned rectifier such that the current in the secondary winding (N2) is cut off by the rectifier action at a low value of the primary current before the switching device (SCR1) is commutated. Such a converter may be used in a television receiver with the transformer (M) comprising the television receiver line transformer and with one secondary winding (N2) supplying the sound circuits of the receiver and a further secondary winding (N3) supplying the picture circuits and, in such application, has the advantage of minimizing the effect of sound load variations upon the size and/or brightness of the picture. <IMAGE>
