摘要
光伏阵列产生的是直流电流和电压,而许多负载都使用交流电,因此需要通过逆变器把直流电变成交流电。随着光伏发电系统(Photo Voltaic System,简称PVS)的日益推广,太阳能PVS中使用的逆变器也越来越多。如何用户对深入了解PVS中的逆变器性能及正确选用逆变器也越来越重要了。本文分类总结了用于PVS中的逆变器;分析研究了这些逆变器在PVS系统中的应用特点;展望了PVS中逆变器向高性能和智能化方向发展的趋势。
The photovoltaic （PV） array and battery produce DC current, however the most loads require AC power,so inverters are needed to convert from DC to AC current.With the rapid development of PV generating technology,inverters are more widely used now.Therefore,it gets more important for us to get known about inverters and how to choose appropriate one for PV application.This paper summarizes the inverter characteristics and special status applied in different PV systems.This work will be very helpful for PV system designing.In the future,the inverters in PV system will become high performance and intelligent.
