Abstract
A novel ride-through approach for matrix converters in adjustable speed drives is presented. The input capacitors are utilized to transfer energy from the spinning inertia of the motor to support the motor flux during grid fault events. The addition of three bidirection switches is required to isolate the input filter capacitors from the collapsed grid voltages. The addition of input switches, a ride-through vector control strategy, and post fault reconnection logic are shown to enable ride-through of many cycle faults without the use of an additional energy storage device. In this paper, the control and reconnect strategies are discussed followed by simulations of the system and the presentation of experimental results. Through a short review of power quality assessments, it is shown that these improvements allow matrix converter-based adjustable speed drives to operate in a majority of real world fault situations.
