Research on the Effects of Pulse Waves Through a Long Cable on Motor Terminal Overvoltage
摘要
Abstract
The reflection of pulse waves through a long cable and the mechanism of motor terminal overvoltage using transmission line theory was analyzed.The pulse wave reflection prosses was simulated with Matlab software. According to the reflection principle,motor terminal over-voltage is the piling up of the incident and reflected wave components.Pusle-lossless cable-motor model was set up in PSpice software, while the critical state and the most likely moment occurring motor terminal overvoltage was studied with the model.And then PWM pulse-lossless cable-motor model was set up to verify that motor terminal voltage reached its maximum as PWM pulse duty cycle is the largest.
