FENG Xiang，YU Yue，LI Cheng，ZHENG Wei，LIU Jianhua
Abstract：The traditional ultra high speed permanent magnet synchronous motor（PMSM）driver uses PWMequivalent sine voltage output，which leads to severe motor heating due to large harmonics，and it cannot be used in situations where the input voltage changes over a large range，such as fuel cells. To reduce the heat gene...
