“…Many potential converters exist for SRMs, including the asymmetric half bridge converter [20], the H-bridge converter [21], the magnetic type converter [22] and the dissipative converter amongst others [23]. The asymmetric half bridge converter is most commonly employed, exhibiting excellent phase independence at the expense of a large number of power electronic devices, requiring two switches and two diodes per phase [20].…”

“…Of the alternatives, the H-bridge, bifilar, and dissipative converters each reduce the number of switches by half, but each has consequent drawbacks and limitations. The H-bridge converter is only suitable for four or multiples of four-phase machines [21]; the bifilar converter employs an extra inductance for each phase, which increases the converter cost and volume [22]; the dissipative converter employs extra resistance to absorb the energy stored in the phase winding, giving rise to reduced efficiency and limited scope of application [23]. Except all the conventional converters mentioned above, some application specific converter topologies for SRM are proposed [24][25][26], which can also be treated as the potential converters.…”

This paper presents a novel converter topology for six-phase Switched Reluctance Motor (SRM) drives, which reduces the number of switches and diodes by half, compared with the conventional asymmetric half bridge converter, but needs no additional energy storage component. A dynamic model of a six-phase SRM is developed in the MATLAB/SIMULINK environment and conventional current chopping and angle position control techniques are applied to the proposed converter, demonstrating successful operation across the full speed range with modified conventional control techniques, lower converter losses and higher system efficiency compared with the asymmetric half bridge converter. Experimental tests comparing two versions of the proposed converter with an asymmetric half bridge are described and verify the predictions of the simulations.

“…Of the alternatives, the H‐bridge, bifilar, and dissipative converters each reduce the number of switches by half, but each has consequent drawbacks and limitations. The H‐bridge converter is only suitable for four or multiples of four‐phase machines [17]; the bifilar converter employs an extra inductance for each phase, which increases the converter cost and volume [18]; the dissipative converter employs extra resistance to absorb the energy stored in the phase winding, giving rise to reduced efficiency and limited scope of application [19].…”
