摘要

A novel micro-inverter topology is designed and analyzed to enhance the stability and efficiency of renewable energy systems. The proposed design integrates a passive buffered forward-flyback full-bridge inverter with a reactive power compensation circuit and a sophisticated control strategy that ensures efficient and stable reactive power management. The DC/DC conversion segment utilizes a quasi-resonant soft-switching controlled forward-flyback converter, which facilitates digital control by precisely timing the switching actions of the transistors. This approach minimizes switching losses and enhances overall system efficiency. The DC/AC conversion is executed through a critical current control full-bridge inverter operating in bipolar mode. This configuration supports bidirectional power flow and provides the flexibility to adjust reactive power dynamically. To verify the theoretical analysis, an experimental prototype is built with an input voltage range of 20 to 60 V and a rated output power of 440 W. The prototype reaches a peak efficiency of 94.12%, thus validating the effectiveness of the proposed micro-inverter topology.
