An Optimized Angle Control Strategy for Doubly Salient Electro-Magnetic Motor Based on the Half-Bridge Converter


Article Preview

The doubly salient electro-magnetic motor (DSEM) suffers from significant torque ripples when operating in the conventional angle control method. To weaken the effects of the torque ripples, the ripple generation mechanism is first analyzed in this paper. Then, the operation principle and steady state of the split-capacitor in DC-link of the half-bridge converter are discussed in detail, thus an optimized control strategy of the half-bridge converter is proposed for the DSEM drives. The simulation and experimental results verify that the optimized angle control strategy can alleviate the torque ripples effectively and improve the motor performance.
