Performance Investigation of Switched Reluctance Motor Driven by Quasi-Z-Source Integrated Multiport Converter with Different Switching Algorithms

Switched reluctance machines (SRMs) have received increasing attention for their many potential uses, such as wind power and electric vehicle (EV) drive systems. The Quasi-Z-source Integrated Multiport Converter (QZIMPC) was recently introduced to improve the reliability of SRM driver through small capacitance values. It is not possible, however, simultaneously energize deenergize two phases in QZIMPC. This phenomenon can significantly increase commutation period which, turn, degrades performance SRM; addition, this causes high-voltage ripples on converter’s capacitors. Two switching algorithms are applied paper, with investigated terms torque ripple peak phase current. based prioritizing control command on-going off-going fulfill required load torque, well accelerate process where possible. achieved without interference high-level controllers, which include speed controllers and/or minimization. Through simulation results, a comparison between presented determine system’s performance.
