摘要
FIELD: electrical engineering; secondary power supplies for radio-engineering, automatic-control, and computing equipment. SUBSTANCE: method uses series regulating element operating in pulse-width modulation mode and turned on during time spaces when instant value of voltage across LC oscillatory circuit, as it crosses zero, becomes lower than desired value of control signal in absolute value and is turned on as soon as it rises above desired value of control signal; to this end, instant voltage across center tap of oscillatory circuit inductance coil is compared with control signal value across comparison unit and regulating element is either turned on or turned off according to results of comparison. EFFECT: improved output voltage waveform of regulated generator and facilitated procedure. 3 dwg
