MOSFET Selection Strategy and Device Adaptation Handbook for AI Solar Microinverters with High-Efficiency and Power Density Requirements
With the rapid advancement of distributed solar energy and AI-driven energy management, AI solar microinverters have become core components for maximizing energy harvest and ensuring grid stability. The power conversion stages, serving as the "muscle and nerve" of the entire unit, provide critical switching and control for key functions such as DC-DC boost, H-bridge inversion, and auxiliary power management. The selection of power MOSFETs directly determines conversion efficiency, thermal performance, power density, and long-term reliability. Addressing the stringent demands of microinverters for ultra-high efficiency, compact size, high reliability, and smart control, this article focuses on scenario-based adaptation to develop a practical and optimized MOSFET selection strategy.
