This study presents the challenges faced while implementing a new converter topology for switched reluctance motor (SRM) drives. A novel converter configuration that can excite the motor directly from the grid supply, i.e., alternating current supply, was proposed in earlier research. The proposed converter topology is designed to draw power directly from an AC grid. This converter is a modified version of the R-dump converter. There are many converter topologies available for excitation of SRM. The uniqueness of the converter topology developed in this research shows that it can use 4 switches per phase, which in turn increases the redundancy of the whole system. Moreover, this topology is well suitable for SRM excitation since the machine coil structure is constructed with 4 coils and 5 terminals. Since this novel converter is having the advantages of operating in AC input voltage, it improves the usefulness of SRM in household applications such as washing machines, hair dryers, and vacuum cleaners. An analysis of real-time implementation challenges faced while realizing the universal R-dump (URD) converter is presented with discussion to overcome the challenges. An experimental setup is made to verify the converter working.

“…Power converter topologies with a large number of power devices are relatively expensive and increase the difficulty of manufacturing [28]. To overcome these inherent drawbacks of complex topologies, several modular power converters have been proposed in [28][29][30]. Reference [28] proposed an SRM modular power converter based on dual-switch modules and dual-wire windings.…”

“…The battery pack is connected to the half-bridge converter as a sub-module and has multiple sub-modules connected, but the bus voltage is reduced and the excitation and demagnetization processes are prolonged. The modular power converter for a four-phase SRM proposed in [30] has the advantage of overlapping current pulses, which can increase the speed of the SRM and minimize the number of power switch modules. In addition, owing to the inherent working mechanism, this modular power converter improves the motor performance throughout the variation range of the motor characteristics.…”

To improve the endurance and charging flexibility of electric vehicle battery packs, this paper proposes a multi-battery block module (MBM) topology for four-phase switched reluctance motors (SRMs), which not only allows flexible electric vehicle operation, but also achieves fast demagnetization and excitation. By integrating the multi-battery block module and photovoltaic (PV)panel into an asymmetrical half-bridge (AHB)converter, the MBM topology is designed to supply a multilevel bus voltage for the SRM drive. To improve the endurance of battery packs, a PV panel is also added to the topology to charge battery packs when the system is stationary. According to the different operation requirements, multiple power supply modes and charging modes can be realized by controlling the power devices in the proposed MBM topology. The simulation results based on the MATLAB/Simulink platform and the experimental results on a four-phase 8 / 6 switched reluctance motor verify the effectiveness of the proposed design.
