FIELD: power supplies for electronic equipment. SUBSTANCE: power supply has inductance coils in secondary winding of line-sweep output transformer for generating pulse voltage whose pulse duration corresponds to that of high-voltage pulse set up across line-sweep output transformer and for sending it to raster central controller; first and second sections of power supply connected between inductance coils and raster central controller for applying positive and negative potential differences to raster central controller by rectification and charge-discharge operations relative to pulse voltage built up across these inductance coils, respectively. EFFECT: provision for eliminating displacement of image over CRT screen due to instability in power supply caused by variations in line sweep frequency. 8 dwg
