POWER SUPPLY AND ITS OPERATING PROCESS Russian patent published in 2007 - IPC H01M12/06 G05F1/56 

FIELD: electrical engineering.

SUBSTANCE: proposed power supply has electrochemical current source, switching member with control unit, and inductive energy storage device with inductance L; electrochemical current supply is shorted out by capacitor of value C_sh; proposed electrochemical current supply uses aqueous solution of electrolyte, gas-diffusion cathode, and internal resistor R whose value is found from expression R = (0.009 - 0.14) (L/C_sh)^0.5; capacitance ratio of electrochemical current supply to shorted-out capacitor is found from expression C_s = (50 - 100)C_sh and capacitance ratio of shorting capacitor to energy storage inductance is found from expression LC_sh = (2/π)²)T², where T is time of energy storage in inductive storage device. Reactor or transformer is used as energy storage device. Proposed operating process involves periodic connection of electrochemical current supply with open-circuit voltage U and maximal load current I to and its disconnection from inductive storage cell by means of switching member; in the process electrochemical cell current and voltage are checked; at current of (0.1 - 0.2)I electrochemical current supply is disconnected from inductive storage cell and at voltage across electrochemical current supply of (0.6 - 0.8U) it is connected to inductive storage cell again.

EFFECT: improved design and enhanced operating reliability of current supply.
