The purpose of this study is to enhance switched reluctance motor (SRM) drive performance by enabling high-frequency operation. A novel auxiliary resonant zero-voltage-transition (ZVT) converter is proposed, aiming for zero-voltage switching with fewer switches than an asymmetric half-bridge topology.
The converter integrates an auxiliary resonant circuit and a main circuit with few switches. MATLAB/SIMULINK simulation and experimental circuits are used to verify its operation, characteristics and functionality.
The proposed converter achieves ZVS for all main switches and diodes, retains asymmetric half-bridge advantages with fewer switches per phase and supports efficient high-frequency operation cost-effectively.
It introduces an innovative auxiliary resonant ZVT converter for SRM drives. Using fewer main switches per phase than an asymmetric half-bridge, with an auxiliary circuit handling little total power, it enables efficient high-frequency SRM drive operation innovatively.
