Patent GB-2124804-A (GB)
Title: Electrical power supply arrangements
Inventor: TALKS RAYMOND
IPC: H02M7/217
Filed: 1982-07-16
Abstract: In an electrical power supply arrangement for a television receiver in which the a.c. mains at input terminals (1,2) is rectified (D1,D2,D5,D6) to produce unidirectional half sine wave pulses which are applied to a series voltage regulator circuit (R1 ,T1) to produce a low voltage d.c. output across a smoothing capacitor (C2) at output terminals (5, 6), the output voltage is determined by a reference voltage diode (D7) in a potential divider (R2,D8,D7). In order to reduce dissipation in the regulator circuit, the regulator transistor (T1) is rendered non-conducting for a substantial period around the peak of each pulse. This is achieved by a control circuit (R3,R4,D9,R5,T2) which places an effective short circuit across diodes (D7,D8) when the pulse voltage rises to a given value. The series transistor (T1) conducts only during periods adjacent the beginning and end of each unidirectional pulse. <IMAGE>
