New open-winding configurations for high-power inverters

New configurations of high-power inverters suitable for AC motor drives and static VAr controllers are presented. A usual method of supplying large AC drives rated at more than several thousands of kilowatts is to combine the outputs of two inverters using inter-phase reactors. However, such inter-p...

Summary:New configurations of high-power inverters suitable for AC motor drives and static VAr controllers are presented. A usual method of supplying large AC drives rated at more than several thousands of kilowatts is to combine the outputs of two inverters using inter-phase reactors. However, such inter-phase reactors have several disadvantages such as losses and acoustic noise. To solve these problems, several new configurations which combine two different type of inverters or converters to both terminals of the open windings are presented.
