Abstract
The matrix converter is a direct frequency conversion device with high input power quality and regeneration capability. As a device without energy storage elements, it has higher power density than PWM inverter drives. However, for the same reason, the AC line side disturbances can degrade its performance and reliability. In this paper, the behavior of the matrix converter drive under abnormal input line voltage conditions has been investigated. A technique to eliminate the input current distortion due to the input voltage unbalance has been developed and its feasibility proven via computer simulations and laboratory experiments. The power line failure behavior has also been investigated and the rapid re-starting capability of the matrix converter drive has been demonstrated via laboratory experiments.
