Application: Micro inverter and modulation method thereof (Patent ID: US20240195323A1)
The patent filed by Sungrow Power Supply Co Ltd describes a micro inverter for a photovoltaic system, consisting of a filter, transformer, and switching circuit. The switching circuit includes multiple first switching circuits and one second switching circuit, converting direct current to alternating current. The second switching circuit is connected to the transformer, which is then linked to the filter, serving as the output terminal of the system. The micro inverter design allows for efficient power conversion and output suitable for solar energy applications.
Additionally, the patent details a modulation method for the micro inverter, involving monitoring voltages, power transmission, and grid voltage. By controlling the second and first switching circuits based on these parameters, the method optimizes wave emission. Calculations are made to determine phase-shift angles within the H-bridge structure of the first switching circuits and external phase-shift angles, influencing the duty cycle of signal pulses for effective wave emission. This modulation method ensures the micro inverter operates efficiently and in synchronization with the power grid, enhancing overall performance in solar energy systems.
