| Abstract: | In this paper, the operation principles of matrix converter used in induction motor drive system are discussed. Space vector modulation and four-stepped commutation policy have been employed as the control techniques of matrix converter. A 2.2kW three-phase to three-phase matrix converter prototype is implemented based on DSP and PLD. Experimental tests in steady-state have been carried out on the prototype. The system performance under abnormal conditions has been analyzed and the influences on power quality have been discussed. |
