DC POWER SUPPLY FOR LOAD Russian patent published in 1994 - IPC

FIELD: off-line power supply systems. SUBSTANCE: power supply has two or more chemical current sources decoupled through semiconductor valves connected to positive terminal of load, controlled semiconductor elements, diodes, pulse transformers. Two controlled semiconductor elements in the form of transistors, two diodes, and pulse transformer per each pair of interconnected chemical current sources are connected into three-terminal LTD circuit. EFFECT: provision for equalizing residual capacitance of power sources running in parallel during discharge due to redistribution of LTD energies of two adjacent chemical current sources by means of three-terminal circuit. 2 cl, 2 dwg
