Application: Power conversion device and control method thereof (Patent ID: US20240195178A1)
The patent filed by Delta Electronics Inc. describes a power conversion device that includes a three-level inverter, capacitors, a balance circuit, a bidirectional DC-DC converter, and a controller. The device is designed for AC-DC power conversion and includes features to maintain equal voltages across the capacitors by controlling the balance circuit based on the capacitor voltages. The controller regulates the balance circuit switches to ensure voltage equality, enhancing the efficiency and stability of the power conversion process.
Additionally, the patent outlines a control method for the power conversion device, detailing steps for controlling the switches of the balance circuit based on the capacitor voltages to maintain voltage balance. The method involves comparing capacitor voltages, regulating duty ratios of control signals, and stopping the balance circuit operation when voltage equality is achieved. By implementing this control method, the power conversion device can effectively manage voltage imbalances, ensuring optimal performance and reliability in AC-DC power conversion applications.
