摘要： A power conversion system includes a first converter effectively connected in series to a second converter. Each converter has a plurality of output levels. A phase-shifted transformer is coupled to the converters. The phase-shifted transformer has a delta-wound winding and an open star winding. The first converter is coupled to the open star winding and the second converter is coupled to the delta winding. The open star winding is configured for direct connection to either of a load or the open star winding of a second phase-shifted transformer, having a delta winding connected to a third converter. One or more DC voltage sources are each connected to the first and second converters by a respective DC link capacitor. Each DC voltage source is connected to a common power grid by an isolated multiphase transformer winding.

摘要： A grid-side transformerless power conversion system configured to perform power conversion between a power grid and a load, the transformerless power conversion system includes a first converter, a first filter, and a second converter. The first converter is configured to convert first AC power provided from the power grid into DC power. The first converter includes a first converter module and a second converter module coupled to the first converter module to form a nested neutral point piloted topology. The first filter is coupled between the power grid and the first converter. The second converter is coupled to the first converter. The second converter is configured to convert the DC power into second AC power and provide the second AC power to the load.
