Modeling and fault modes investigation of a power sharing AC drive

So as to reduce size, volume, weight and increase efficiency of power supplies for electrical sequential loads, authors propose to analyze functioning and disfunctioning of two converter topologies: inverter + power sharing system; matrix converter. A system with two electrical machines is analyzed through simulations from the control point of view and the design point of view considering over-current conditions constraints. Theses preliminary results enhance the possibility to use matrix converters.
