Abstract
An electrical power converter for an incoming AC transformer connected to a multiphase power source and having multiple secondary windings. Each secondary winding is connected to multiple switching cells, each of which functions like a matrix converter. The secondary windings can be either single or multi-phase and more than one transformer can be provided such that the multiple secondary windings can be distributed among individual transformers. The output of at least two of the switching cells are connected in series. The switching cells can be either bi-directional or unidirectional and can also have a three-phase input. A combination of IGBTs and diodes can form the switching cells.
