BI-DIRECTIONAL POWER CONVERTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18271581 titled 'BI-DIRECTIONAL POWER CONVERTER
Simplified Explanation:
This patent application describes a bi-directional power converter system that enables the transfer of power between an electric vehicle (EV) and a power grid. The system includes a control unit, a charging device, and a unique bi-directional power converter with multiple stages for efficient power conversion.
- The bi-directional power converter consists of an isolated DC-DC converter with three stages: a first stage that converts DC voltage into high frequency AC voltage, a second stage that converts high frequency AC voltage back into DC voltage, and an intermediary stage with a high frequency transformer.
- The second stage is capable of converting the high frequency AC voltage into DC voltage with an amplitude of V2 or 2V2, and then converting it into a multi-level high frequency AC voltage.
- The intermediary stage is electrically coupled to the first and second stages and includes a high frequency transformer with a turns ratio of V1:V2.
Key Features and Innovation:
- Isolated DC-DC converter with multiple stages for efficient power conversion.
- Capability to convert high frequency AC voltage into DC voltage with varying amplitudes.
- High frequency transformer in the intermediary stage for effective power transfer.
Potential Applications:
The technology can be used in electric vehicle charging stations, smart grid systems, renewable energy integration, and energy storage systems.
Problems Solved:
The system addresses the need for efficient power transfer between EVs and the power grid, as well as the demand for bi-directional power conversion in modern energy systems.
Benefits:
- Improved efficiency in power transfer.
- Enhanced integration of EVs with the power grid.
- Flexibility in power conversion for various applications.
Commercial Applications:
