Abstract
A multi-level parallel phase power converter has a power source, a converter, and an electrical node. The converter includes multiple converter modules. Each of the converter modules has multiple multi-level power converters, a poly-phase interphase inductor, and a set of poly-phase power summing connections. The summed power of each of the multiple converter modules are connected together to form a single poly-phase power converter.
Claims15
A multi-level parallel phase power converter comprising:
- a power source;
- a power converter coupled to said power source and having a plurality of converter modules comprising multi-level power converters, a poly-phase interphase inductor, and poly-phase output connections, each of said multi-level power converters having a power line connected to said poly-phase interphase inductor;
- and
- an electrical node connecting each of said poly-phase output connections, thereby forming a single poly-phase power converter output.

A method for converting power comprising the steps of;
- inputting a DC power into a multi-level parallel phase converter comprising a plurality of converter modules;
- each of said converter modules converting said DC power signal into a poly-phase staircase wave power signal;
- combining each of said poly-phase staircase wave power in an interphase inductor, thereby creating an output power;
- and
- filtering said output power signal in a passive filter, thereby creating a filtered output power.
