DIRECT VOLTAGE REGULATOR WITH PULSE CONTROL Russian patent published in 1994 - IPC

FIELD: secondary sources of power supply. SUBSTANCE: direct voltage regulator with pulse control has key controlling element, LCD filter, control unit including comparator, RS flip- flop, logic 2AND gate, source of reference voltage, generator, capacitor, two voltage dividers. Controlling element produces stationary control pulses, i.e. of equal duration with invariable output voltage and frequency. Frequency of these pulses is determined by frequency of generator and their duration depends on changes of output voltage. Voltage regulator may have three versions: step-down, step-up and inverting. EFFECT: reduced dimensions, improved operational stability. 2 cl, 2 dwg
