Method and apparatus for controlling voltage reflections using a motor controller |
摘要 |
A method and apparatus for eliminating greater than twice over voltage by altering firing signals provided to a PWM inverter. The signals are altered by either limiting their maximum and minimum on-times or eliminating signal changes in a symmetrical fashion so that the overall fundamental component and magnitude of a resulting low frequency alternating voltage is substantially unaltered.
