POWER SUPPLY SYSTEM FOR RING ENERGY STORAGE CIRCUIT Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: power supply system for ring energy storage circuit is formed from electromagnets, each of them being load of thyristor converter connected in series with it. Thyristor converter is provided with passive filter, current pickups of load and input current, thyristor with starting unit. Discharge resistor is between output units of clamping device through additional thyristor which controlling electrode is coupled to first output of starting unit. Second output of starting unit is coupled to starting input of switch. Third output of it is connected to phase control system of thyristor converter. Adjustment input is linked to output of pickup of load current, second controlling input to output of pickup of input current and first controlling input to external starting device. EFFECT: enhanced operational reliability. 2 dwg
