Outline of Final Research Achievements

This research established a technique for reducing an electromagnetic interference by applying a zero-sequence voltage in power converters. This technique uses an appropriate zero-sequence voltage and can apply not only a motor is nearly at zero speed but also the motor is driving a load at any speed. Concrete results are the following three points. (1) We proposed to add the zero-sequence voltage to an inverter reference which is controlled as a function of the inverter output frequency considering that the counter EMF of the motor is directly proportional to the motor speed. (2) The detailed simulation results in the rotation state of the motor showed clearly that the proposed technique could reduce the leakage current not only the motor was nearly at zero speed but also the motor is driving a load at any speed. (3) The experimental results verified that the proposed technique could reduce about 30% of the leakage current compared with the conventional method.
