Abstract
In this paper, the RC filter for mitigating the output overvoltage of the 3-level 3300V 4MW inverter is described. The descriptions on power circuit and overvoltage phenomena are presented. The output transformer which may be used to obtain the higher output voltage, makes the filter design difficult because the parameter measurements are not easy and the accuracy may be poor. So, this paper presents several preliminary results on the output overvoltage with or without transformer to investigate the overall system characteristics. Some experimental results are also provided when the designed filter is applied.
