VOLTAGE CONVERTER Russian patent published in 1995 - IPC

FIELD: radioelectronics. SUBSTANCE: voltage converter has regulating transistor 1, current-restricting resistor 2, protection transistor 5, lock transistor 6, two modulators 7 and 8, pulse oscillator 9, two separating capacitors 10 and 12, two detectors 11 and 13, operational amplifier 14, four comparators 17, 32, 34, 35, AND gate 18, two flip-flops 19 and 33, three control switches 20, 31, 43, three reference voltage sources 21, 27, 28, capacitor 23, two current generators 36 and 37, error amplifier 41, unit 45 for controlling modulators. Specific amplitude square-shaped signals may be applied to input of operational amplifier 14 from output 39 or saw-tooth voltage signals may be applied from output 38. In this case, pulse-width modulation is available and different circuits of converter application may be got. EFFECT: improved efficiency. 6 dwg
