摘　　要：电机绕组的动态电压是影响其电流变化能力的直接因素。为了提升电机的转矩响应速度,从直流电压利用率的角度分析串联绕组拓扑的动态电流控制能力。首先,从拓扑结构出发,相比于三相半桥拓扑,串联绕组拓扑将直流电压利用率提升了73%,这使得其动态电压更加充裕。然后,在不同的转速工况下,分析串联绕组拓扑、三相半桥拓扑以及采用电压修正策略的三相半桥拓扑的动态电流控制性能。最后,经仿真与实验证明,若采用电压修正策略来增大三相半桥拓扑的动态电压裕度,其只在转速接近额定转速时效果才凸显,且提升有限。而采用串联绕组拓扑,其在电压深度饱和下的电流动态响应时间将显著减小。Dynamic voltage on the electrical motor winding is the direct factor to impact the winding current variation capability.In order to enhance the torque response speed in electrical motor,this paper analyzes the dynamic current control capability of the series-end winding topology(SWT)based on DC-link voltage utilization.Based on the topology structure,SWT can increase DC-link voltage utilization by 73%than regular three-phase half-bridge topology,bringing more sufficient dynamic voltage.Then,with different rotational speeds,the dynamic current control capability for SWT,and the three-phase half-bridge inverter with and without voltage modification method are analyzed.Finally,with simulation and experimental results,it is validated that only with voltage modification method to increase the dynamic voltage capability for three-phase half-bridge inverter,the effect is limited and it is only for the speed close to rated value.But with SWT,the dynamic response time of current will be obviously reduced in voltage deep saturation status.
