High performance motor drive using matrix converter

The matrix converter is superior to the PWM inverter drives because of its regeneration ability and sinusoidal input current. Therefore, it meets the stringent energy-efficiency and power quality requirements of the new century. This paper describes the basic operating principles and control method of the matrix converter, and reports the detailed experimental operating characteristics of an 11 kVA matrix converter drive over its full operating range. Through the experimental operating characteristics, the paper illustrates the feasibility of the matrix converter drive as an environment-friendly future-generation drive.
