Abstract

A switching regulator for a television display apparatus includes a controllable switch 16 coupled to a source of unregulated direct voltage (at 12). The switch is operated at the deflection rate to produce a pulsating direct voltage. A filter including a series choke 18 and a shunt capacitor 20 has its input (A) coupled to the switch 16 for filtering the pulsating direct voltage to form a direct voltage for operating the television display apparatus. An integrator 48, 50 has its input coupled to the input A of the filter for averaging the pulsating direct voltage. A control circuit 30 has an input (C) coupled to the integrator and an output (collector of 34) coupled to a control electrode of the controllable switch 16 for maintaining the average of the pulsating direct voltage constant.
