并详细地讨论了改善换向所采取的“反阻尼”措施与“反变压器电势”措施。
The methods of "anti-damping" and "anti-transformer-potential" for improvement on commutation are discussed in detail as well.
本文采用虚拟中点的方法来识别反电势过零点，然后对过零点进行处理得到无刷电机换向的六个关键位置。
This paper USES "virtual neutral point method" to measure the "zero crossing", then the soft deal "zero crossing" to get the six key position to commutate.
