| Abstract: | In this paper,the multi-pulse converter based on high-frequency-operated transformers which demonstrated considerable reduction in size and weight of the multi-pulse transformer,due to higher frequency operation,is modeled and mathematically analyzed.It provides theoretical investigations of the principle of the reduction in the 5th and 7th harmonic components in utility input current.The models of both power cells and 12-pulse rectifier connected in series are defined using the switching function framework... |
