摘　　要：在光伏逆变系统中,内部电磁干扰是影响其工作稳定性和可靠性的重要因素,能否有效地控制内部电磁干扰决定着系统的成败。文章以一款3 kW离网光伏逆变器设计为例,分析了系统内部主要电磁干扰的分布,并提出了具体解决方案。In the photovoltaic inverter, electromagnetic interference is one of the key factors, which affects the stability and reliability. How to control the internal electromagnetic interference effectively is a decision of success or failure of the sys- tem. The paper, taking a 3 kW photovoltaic off-grid inverter as an example ; analyzes the distribution inside of the main electromagnetic interference. Specific solutions are worked out.
