Applications include grid connected electronics, photovoltaic inverter systems, electromechanical motor drives, and telecommunications rectifiers.
This technology addresses the energy losses in grid interfaces.
Improving the efficiency in electrical power conversion reduces unneeded power losses. This invention provides a multi-phase power converter architecture with a robust AC interface, enabling an improvement in efficiency over traditional implementations. The design inherently provides the capability for bidirectional and reactive power control capability for each phase independently, or in unison for three-phase systems. These features are useful for providing smart-grid participation and improved reliability in uncertain voltage conditions. Each input / output port (phase) is logically connected in series, and can scale to the required number of input/output connections for applications in motor drives and ac-ac converters.
- Provides reduced power losses for a power converter with multiple outputs, while improving functionality and reliability for the AC interfaces.
