OFF-LINE INDUCTION-GENERATOR POWER SUPPLY Russian patent published in 2000 - IPC

FIELD: power stations with induction generators. SUBSTANCE: power supply has induction generator 1 driven by internal-combustion engine 4 and provided with field capacitors 2, as well as voltage regulator 3. In addition, it has forced-excitation device incorporating ignition coil 5, control button 9, rectifier diode 10, storage capacitor 11, dynistor 12, and relay 14 with break contacts 13. One of two terminals of primary winding 7 in ignition coil 5 is connected through make contacts of control button 9 to minus terminal of storage capacitor 11 and its other terminal, to anode of rectifier diode 10 whose cathode is connected to plus terminal of storage capacitor 11 and to anode of dynistor 12; cathode of the latter and minus terminal of storage capacitor 11 are connected through break contacts 13 of relay 14 to two phase leads of induction generator; relay winding is connected to mentioned phase leads. EFFECT: improved reliability of power supply. 1 dwg
