INRUSH CURRENT START-UP CIRCUIT FOR A TELEVISION RECEIVER ABSTRACT OF THE DISCLOSURE A start-up circuit for a television receiver includes a circuit for rectifying the AC line voltage and a filter for providing a smoothed DC voltage. When the receiver is turned on, an initial interval exists in which inrush current flows into the filter. A magnetically coupled winding of an inductor in the path of the inrush current develops an alternating current potential during the initial interval. This potential is rectified and provides a start-up operating voltage for the television receiver. - 1 -
