POWER CONVERSION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240243671 titled 'POWER CONVERSION DEVICE
The abstract describes a power conversion device that includes a converter, an inverter, and a control circuit that controls them. The control circuit generates first control signals for the converter based on a first carrier wave, and second control signals for the inverter based on a second carrier wave with a different frequency and phase. The frequencies of the carrier waves have a predetermined relationship based on the current of a capacitor connected between the converter and the inverter.
- The power conversion device includes a converter, inverter, and control circuit.
- The control circuit generates first control signals for the converter and second control signals for the inverter.
- The first and second control signals are based on different carrier waves with different frequencies and phases.
- The frequencies of the carrier waves have a predetermined relationship based on the current of a capacitor.
- This technology optimizes power conversion efficiency by coordinating the control of the converter and inverter.
Potential Applications: - Renewable energy systems - Electric vehicles - Industrial power systems
Problems Solved: - Improved power conversion efficiency - Enhanced control of converter and inverter
Benefits: - Increased energy efficiency - Better performance in various applications - Reduced energy costs
Commercial Applications: Title: Advanced Power Conversion Technology for Renewable Energy Systems This technology can be used in solar power plants, wind farms, and electric vehicle charging stations to improve energy efficiency and reduce operating costs.

Original Abstract Submitted
a power conversion device includes a converter, an inverter and a control circuit that controls them. the control circuit generates: first control signals that control the converter, on the basis of a first carrier wave; and second control signals that control the inverter, on the basis of a second carrier wave having a frequency and a phase that are different from those of the first carrier wave. the frequency of the first carrier wave and the frequency of the second carrier wave have a predetermined relationship therebetween based on a current of a capacitor connected in between the converter and the inverter.
