一种开关磁阻电机零压分散调制策略
Zero-voltage Dispersion Modulation Strategy for Switched Reluctance Motor
摘要
Abstract
Aiming at the current fluctuation and torque ripple problem caused by traditional voltage pulse-width modulation(PWM)modulation strategy of switched reluctance motor,a zero-voltage dispersion modulation strategy is proposed.By optimizing the insertion time of zero voltage during the switching cycle,the current pulse number can be increased and current ripple and motor torque ripple can be reduced without increasing the switching frequency and switching loss of the device.The definition of current fluctuation under dynamic conditions is proposed,and the current fluctuation and torque fluctuation of zero-voltage modulation strategy and traditional modulation strategy are compared and analyzed.The simulation model and experimental platform of 6/4 pole switched reluctance motor based on torque distribution function are established to verify the feasibility of the method.Compared with the traditional voltage PWM modulation strategy,the zero-voltage distributed modulation strategy proposed in this paper has better suppression effect on the torque ripple of switched reluctance motor under different loads and speeds.关键词
