摘要

本文提出了一种基于单一电流传感器的永磁无刷直流电动机(PMBLDCM)驱动器，该驱动器配备了变速、变扭矩应用(如风扇、泵和鼓风机)的电能质量(PQ)控制器。一种非隔离的单端初级电感变换器(SEPIC)通过二极管桥式整流器(DBR)从交流电源馈电，用作交流电源的电能质量控制器。提出了负载转矩控制和转速控制分别采用单电流传感器控制和直流链路电压控制策略。针对1.1 KW, 1400 rpm, 7.4 Nm的PMBLDC电机设计并建模了所提出的转换器和控制器。在MATLAB/Simulink中对稳态和瞬态条件下的性能进行了仿真，验证了所提概念的有效性。

Single current sensor PMBLDC motor drive with power quality controller for variable speed variable torque applications

This paper proposes a single current sensor based drive for permanent magnet brushless DC motor (PMBLDCM) equipped with power quality (PQ) controller for variable speed variable torque applications e.g. fans, pumps and blowers. A non-isolated, single-ended primary inductor converter (SEPIC) fed from AC mains through a diode bridge rectifier (DBR) is used as power quality controller at AC mains. The load torque and speed control is proposed through a single current sensor control and DC link voltage control strategies respectively. The proposed converter and controllers are designed and modelled for a 1.1 KW, 1400 rpm, 7.4 Nm PMBLDC motor. The simulated performance under steady state and transient conditions in MATLAB/Simulink, are presented to demonstrate the effectiveness of the proposed concepts.
