SECONDARY POWER SUPPLY Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: power supply has master oscillator 1, switch 2 with forward and inverse outputs, sawtooth voltage generator 3, pulse modulator 4, push-pull voltage converter 5, feedback unit 14. Generator 3 is built around three capacitors 6,7, and 15, two resistive dividers 8,9 and 12,13, and two diodes 10 and 11. EFFECT: improved accuracy and stability of output voltage, elimination of starting currents due to "soft" starting conditions which improves reliability of power supply. 1 dwg
