大功率光伏低噪音灌封电感的设计

The design of high power pv low noise inductance encapsulation

随着光伏能源的快速发展,无论是户外的光伏电站,还是户用以及工商业屋顶的大功率逆变器对设备的噪音提出了越来越高的要求,而对逆变器设备中最重要的元器件电感的噪音关注也是越来越高了。本文提出了一种大功率光伏灌封电感低噪音技术的设计思路,此思路有效的解决了目前光伏灌封电感的噪音问题,同时给其他领域的电感设计也提供方法。

With the rapid development of photovoltaic energy,no matter the outdoor photovoltaic power station,or household and industrial and commercial roof high-power inverters put forward higher and higher requirements on equipment noise,and the most important component of the inverter equipment inductance noise is also more and more attention.This paper presents a design idea of low noise technology for high power PV potting inductance,which effectively solves the noise problem of pv potting inductance at present and provides a method for inductance design in other fields.
