| Abstract: | Aiming at the fact that the excitation current build-up speed of the bearingless switched reluctance motor is too slow during commutation, this pap er proposes a simple structured boost power converter, when the motor is commutati-on,it uses the winding demagnetization en ergy to quickly establish the excitation current for the latter phase winding, and r-ealizes the low torque ripple operation of the motor on the basis of ensuring the stable suspension of the motor. The topol-ogyand working status of the powe r converter are analyzed. On this basis, a 12/8-pole dual -winding wide rotor tooth beari-ngless switched reluctance motor drive system based on the new boost power converter is constructed, Through Matlab/Sim-ulink system simulation and experiment platform, the feasibility and effectiveness of the power converter are verified. |
