POWER CONVERTER AND CIRCUIT ARRANGEMENT WITH SUCH A POWER CONVERTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18404059 titled 'POWER CONVERTER AND CIRCUIT ARRANGEMENT WITH SUCH A POWER CONVERTER
The power converter described in the patent application consists of a series circuit with first and second intermediate circuit capacitors connected in parallel to first and second half-bridges. The first center switch is connected to the center point of the first half-bridge to provide a first phase, while the second center switch is connected to the center point of the second half-bridge to provide a second phase. The first and second center switches are connected to provide a third phase.
- The power converter utilizes a space vector modulation to control the first and second half-bridges, as well as the first and second center switches.
- An evaluation unit adjusts the voltage ratio between the first and second intermediate circuit capacitors.
Potential Applications: - Renewable energy systems - Electric vehicles - Industrial motor drives
Problems Solved: - Efficient power conversion - Precise voltage control
Benefits: - Improved energy efficiency - Enhanced system performance
Commercial Applications: Title: Advanced Power Converter for Renewable Energy Systems This technology can be used in solar inverters, wind turbines, and electric vehicle chargers, offering higher efficiency and better control over voltage levels.
Questions about the technology: 1. How does the space vector modulation technique improve the performance of the power converter? 2. What are the key advantages of using intermediate circuit capacitors in this power converter design?
Original Abstract Submitted
A power converter and a circuit arrangement. The power converter has a series circuit, including first and second intermediate circuit capacitors, connected in parallel to first and second half-bridges. A first terminal of a first center switch is connected to a center point of the first half-bridge and is configured to provide a first phase. A first terminal of a second center switch is connected to a center point of the second half-bridge of the power converter and is configured to provide a second phase. A second terminal of the first center switch and of the second center switch are connected and configured to provide a third phase. An evaluation unit is configured to actuate the first and second half-bridges, the first center switch, and the second center switch based on a space vector modulation and to adjust a voltage ratio between the first and second intermediate circuit capacitors.
