A new converter topology and control scheme for switched reluctance machines in application to wind energy conversion system

Asymmetric half bridge converter has been considered as a benchmark topology for driving the switched reluctance machine (SRM). However the lack of its commercialization in the form of a single module makes this converter to suffer from higher cost, lower speed and lesser efficiency. This research paper presents a new converter which uses the Standard full bridge inverter along with one extra leg for star connected phases. A novel control scheme has been devised for the torque ripple minimization. The proposed converter and control system has been simulated in application to a wind energy conversion system (WECS) driven by a permanent magnet reluctance generator (PMRG). The simulation results confirm the effectiveness and superiority of the novel system in contrast with the existing one.
