Abstract

In this article a deadband compensation scheme is proposed for matrix converter driven open-ended three phase machines. The open-ended machine driven by two matrix converters has several benefits. Appropriate switching combinations eliminate the common-mode voltage. Very small common mode voltage remains due to the non-ideal behavior of the switches due to the deadband effect. A method is proposed to remove the common mode voltages generated due to deadband effects. By eliminating the common mode voltage from the three phases of the machine the motor bearing current is entirely removed. By using matrix converters for power conversion bulky capacitors are eliminated from the drive.
