FIELD: electricity. ^ SUBSTANCE: additional capacitor and diode are introduced to self-commutated inverter; at that, one of the outputs of additional capacitor is connected to connection point of capacitor of filter with protective throttle, and the other output is connected to cathode of additional thyristor and to anode of additional diode; anode of additional thyristor is connected to sealing-off, and cathode of additional diode is connected to input pin of filter throttle. ^ EFFECT: higher reliability of self-commutated inverter owing to increasing the circuit time for rehabilitation of inverter and use of energy of filter throttle during accelerated overcharge of filter capacitor, and elimination of formation of short circuit of power source at failures of additional thyristor. ^ 1 dwg |
