| Abstract |
To optimize load commutated converter drives synchronous machine dimensions are of fundamental importance. In particular damper winding parameters determine system behaviour. Using accurate models presented in previous papers commutation of synchronous machines with symmetrically wound cylindrical rotor and cylindrical rotor with exclusive d-axis winding is examined. The distribution of currents in the damper winding shows how constant magnetizing current is maintained which ensures safe commutation. The absence of a winding in the rotor q-axis means magnetizing current variations which cause considerably longer commutation time. Passive load variation influences DC voltage while at small firing angles the overlap angle may exceed cycle time. Fast processing and accuracy make the used software a powerful tool for drive design and analysis. |
