Abstract
A power conversion system 10 which comprises a controller 12 and conversion assemblies 46, 48 which selectively rectify and invert an electrical signal. Conversion assemblies 46, 48 respectively comprise a plurality of integrated gate bipolar transistor assemblies. The power conversion system 10 is effective to convert DC current to AC current, convert AC current to DC current, and to control the output frequency of a received electrical signal to a conventional operating range.
Claims7
A power conversion system comprising:
- a first power conversion portion which selectively rectifies a signal;
- a second power conversion portion which selectively modifies a frequency of said signal;
- a controller which is coupled to said first and second power conversion portions, and selectively causes one of a rectification and a frequency modification to be accomplished;
- at least one interface assembly which is selectively coupled to said controller and which receives said signal into said power conversion system;
- and
- a bus assembly which is coupled to said controller, to said first and to said second conversion assembly, said bus assembly being effective to couple said first conversion assembly to said second conversion assembly;
- wherein said first and said second power conversion portions each comprise at least one integrated gate bipolar transistor assembly and said power conversion system selectively converts power provided from a plurality of diverse power generation assemblies.
