Brushless DC motor in 180° conduction operation may occur the phenomenon the same leg short, in order to solve this problem, the traditional non-isolated three-phase inverter is replaced, and the high-frequency link matrix inverter is studied for driving brushless DC motor 180° conduction operation. In this paper, the non-isolated three-phase inverter is replaced for the brushless DC motor in the...
Aiming at the large instantaneous common-mode voltage in traditional space vector modulation strategy for two-stage matrix converter (TSMC), on the basis of analyzing the laws of common-mode voltage, an improved modulation strategy to reduce common-mode voltage was proposed. To suppress common-mode voltage effectively, the sector of rectifier stage was doubled into twelve sectors from six sectors,...
