摘要

由PWM引起的高频共模电压分量是电机驱动中常见的问题。它会引起电磁干扰、绕组绝缘过电压应力和轴承电流，从而导致过早损坏和故障。通过适当选择PWM策略可以减轻轴承电流问题。

PWM Strategies with Reduced Bearing Currents for Five-Phase Motors

High frequency common-mode voltage components caused by the PWM is a common problem in motor drive. It causes electromagnetic interference, over voltage stress in the winding insulation and bearing currents, which can cause premature damages an failures. The bearing currents problem can be mitigated by a proper selection of the PWM strategy.
