POWER SUPPLY SOURCE OF PULSE LOAD Russian patent published in 1995 - IPC

FIELD: current conversion. SUBSTANCE: power supply source of pulse load has storage battery 1 and capacitive accumulator 2 connected in parallel. The latter is manufactured on base of pulse capacitors of superhigh energy capacity. Thyristor 4 and current limiting resistor 5 shunted with backward diode 3 are placed in series in branch of accumulator. Control circuit of thyristor has starting button 6 and second current limiting resistor 7. Technical result is achieved due to disconnection of accumulator from storage battery by means of thyristor key and is manifested in increase of service life of accumulator and power supply source as a unit thanks to presence of accumulator between discharge pulses under voltage reduced 1.5-2 fold and more as compared with emf of storage battery. EFFECT: prolonged service life of power supply source. 1 dwg
