Abstract

This report furnishes the brushless DC motor (BLDC) performance when fed by multi level inverter is compared with voltage source inverter (VSI) fed BLDC motor. Total harmonic distortion (THD) of stator currents and back EMF's of BLDC Motor for these two inverter topologies are compared. Over past years for high power and medium voltage control applications multi level inverters are employed. To obtain higher levels of voltage different types of multilevel inverters are used. Among them, Cascaded H-bridge multi level inverters are mostly used due to its advantages over other. Here experimental results of a voltage source inverter fed BLDC motor performance are compared with cascaded H-bridge multilevel inverter driven BLDC motor performance.

用多电平逆变器提高永磁无刷直流电动机的性能

本文比较了采用多电平逆变器供电的无刷直流电动机与电压源逆变器供电的无刷直流电动机的性能。比较了两种逆变器拓扑结构下无刷直流电机定子电流和反电动势的总谐波畸变(THD)。在过去的几年里，大功率和中压控制应用采用了多电平逆变器。为了获得更高的电压水平，使用了不同类型的多电平逆变器。其中，级联h桥多电平逆变器由于其优点被广泛使用。本文将电压源逆变器驱动的无刷直流电机性能与级联h桥多电平逆变器驱动的无刷直流电机性能进行了实验比较。
