Analysis Performance of Capacitor Voltage in C-Dump Converter for SRM Drive

摘要

Switched reluctance motors have various converter topologies to control power, speed & operation. Conventional C-dump converter topologies will be discussed in this paper. Ease of control, simple construction, and low cost are the basis for choosing the type of converter. SRM is the best competitor for induction motors because the high torque ratio to Switched Reluctance Motors is more desirable than Induction Motors. This converter provides fast magnetization and rapid demagnetization of phase windings which prevents motor operation in generating mode. This avoids the formation of negative torque ripples. It also utilizes the energy stored in the winding phase & it can be a feedback to the source. Several new topology modifications from C-dump are able to utilize this stored energy to get out of the motor winding of the next stage.
