Weba) Describe relative merits and demerits of four quadrant dc drives employing non- [7M] circulating and circulating dual converters. b) A separately excited DC motor is operating from a single phase semi converter at a [7M] speed of 1200 rpm, with input voltage of 320 V and back emf of 100 V. WebThe band width decreases when the armature has increased ripple and speed is high. Satisfactory Commutation in DC Motor can be achieved in a dc motor by the following modifications: 1.The peak value of the armature current can be controlled by increasing the pulse number of the converter. Additional inductance in the armature circuit helps ...

Doubly fed electrical generators are similar to AC electrical generators, but have additional features which allow them to run at speeds slightly above or below their natural synchronous speed. This is useful for large variable speed wind turbines, because wind speed can change suddenly. When a gust of wind hits a wind turbine, the blades try to speed up, but a synchronous generator is locke…
