Pattern #2: With this pattern, known as Hardware-Determined, one PWM channel remains constant for the entire PWM period. Consequently, the number of switching times for this pattern is less than pattern #1. As a result, switching losses are reduced with Pattern #2. ...

The rectifier is constituted by a 2-level PWM converter having a forward converting function and a reverse converting function. The AC power supplied to the motor car is converted into a DC power. 展开 收藏 引用 批量引用 报错 分享 全部来源 求助全文 掌桥科研 相似文献...
Parasitic capacitive couplings create a path to discharge current in the rotor and bearings results in premature bearing failure. In many new and retrofit industrial applications the PWM inverters and motors must be at separate locations thus requiring long motor cable, which contributes over voltage ...
