Abstract :
This paper introduces a space vector PWM technique for a direct matrix converter based three-phase open-end winding AC machine drive. With the proposed PWM technique, the following simultaneous capabilities of the open-end winding drive system are achieved: 1) Machine phase voltage up to 1.5 times the input phase voltage in the linear modulation, 2) Controllable grid power factor, and 3) Elimination of the high-frequency common-mode voltage at the machine terminals. Elimination of the high-frequency common-mode voltage results in elimination of the high-frequency bearing current and reduced conducted EMI. The proposed modulation scheme is implemented on a dSPACE and FPGA based control platform. Experimental results on a hardware prototype verify the above mentioned capabilities of the drive system.
