A Novel Driving Method for Switched Reluctance Motor With Standard Full Bridge Inverter

Abstract

This paper proposes a new driving method for a switched reluctance motor (SRM) by using a standard full bridge. The windings in the SRM are connected in series to build a ring structure, where a controllable DC source is inserted. Based on the new structure, the theoretical analysis and calculation are made to determine the control parameters. Besides three-phase SRM, the new idea can also be applied to the SRMs with four and five phases. The new driving method is compared with the conventional method by simulation. The results show that with the new method, the ripple of torque and speed in the SRM reduces. The influence of the proposed method on the power rating and losses is then analyzed. The validation is also made to verify the application of the new method and the difference between the conventional driving method and the proposed method. The measured results match the simulated results well.

An Improved Buck-boost Power Converter for Switched Reluctance Generator Drive

“…The conduction and switching losses of an IGBT and diode, according to [28,29,30], can be as In order to optimize the losses of power devices, a solution is to adopt SiC module in the converter. The switching losses of the SiC module are less than half of the Si module, and this difference increases in high switching frequency [31].…”

A Review of the Power Converter Interfaces for Switched Reluctance Machines

“…Among the hard-switching converters, the Bridge converters are the most common ones and four topologies are usually considered: the asymmetrical half-bridge, the shared phase winding, the shared switch and the full-bridge (H-bridge). A more recent topology [33,34] that uses a conventional three-phase bridge converter (inverter) can also be considered as a Bridge converter. In turn, the Capacitive topologies usually include the C-Dump, the Sood, the Split DC and the Buck-Boost.…”

“…In the conventional three-phase bridge topology, represented in Figure 6, a conventional three-phase inverter is used, connected to the windings that are connected in series, allowing a permanent circulating current [33,34]. The main advantage of this topology is the possibility of using a standard three-phase inverter, with no need of changing the internal structure of the machine or the excitation method.…”
