Method for starting up a converter drive comprising an intermediate current link converter with phase sequence quenching |
摘要 |
For setting in operation a converter drive for an asynchronous machine with an intermediate-current link and phase-sequence quenching, the commutations in the inverter are synchronized with the commutations in the controlled rectifier and/or all commutating capacitors are discharged before the start-up and/or the direction of commutation is cyclically changed during the startup. This makes it possible to start up the converter also if the intermediate-link current has gaps, and the asynchronous machine is loaded only with hunting torques.
