Modular and scalable power conversion system for aircraft

A power conversion module, said power conversion module comprising:

• an input assembly;
• a three-phase bridge;
• an output assembly including at least one isolation device;
• and
• a control unit, wherein said control unit
• controls said three-phase bridge via a driver, and
• controls a state of said at least one isolation device within said output assembly, and
• controls said power conversion module to function in one of:
• an independent mode with a second power conversion module, so that said power conversion module drives only a first system and the second power control module drives only a second system,
• an inter-relational mode with a second power conversion module, so that said power conversion module drives a system and, upon a failure of said power conversion module, said second power conversion module will drive said system, and
• a scalable mode with a second power conversion module, so that said power conversion module and said second power conversion module are connected in parallel to provide an additive output.

A method for converting power, said method comprising:

• controlling a plurality of power conversion modules to function independently of each other to supply a plurality of systems, wherein at least one of said plurality of systems receives power only from at least one of the plurality of power conversion modules;
• controlling said plurality of power conversion modules to function in an inter-relational mode in which at least one power conversion module from said plurality of power conversion modules drives a system and, upon a failure of said at least one power conversion module, at least another power conversion module from said plurality of power conversion modules will drive said system;
• and
• controlling said plurality of power conversion modules to function in a scalable mode in which at least two power conversion modules of said plurality of power conversion modules are connected to provide an additive output
• wherein at least two power conversion modules are each designed for separately supplying a lower power independently and supplying a higher power together in said scalable mode.
