<p>1. A thyristor voltage inverter, specifically for supplying asynchronous motors, comprising a thyristor-diode bridge and a commutation circuit, wherein parallel to the thyristor-diode bridge (3) there is connected a commutation circuit (2a) which is composed of a thyristor that switched off using a gate (GTOR) or a power transistor with a diode (DO) that is inversely-parallel connected thereto and a source of direct current (UKR), the said commutation circuit (2a) and the thyristor-diode bridge (3) being supplied with power via a circuit breaker (2) that is serially connected to one of the poles of the source (1) of supply voltage.<IMAGE></p> |
