摘要
提出了基于UC 3854的太阳能逆变器的控制方案,可将光伏能量转换为交流电为独立负载供电及并网。利用UC 3854的电流控制功能和运算放大器在芯片内实现了双闭环控制,装置结构简单,操作方便,易于高频化,能实现无冲击并网。
A research on photovoltaic inverter controlled by UC3854 is presented in this paper. Photovoltaic energy can be transformed into AC for local load or net grid by the use of this controller. Both voltage and current loop circuits are implemented inside by the current control function and amplifier of UC3854. With a simple structure the inverter is convenient to be operated, easy to be realized with high frequency and there is low current stress in the process of net grid.
