摘要:
］在光伏发电系统中为了控制蓄电池的充放电的稳定性，保护系统的安全性，设计了一种以非隔离型的Buck/Boost拓扑结构为主电路的DC-DC变换器、设计了电路的参数，提出了基于电压、电流双闭环的控制算法，采用微处理器TMS320F28335为控制核心，开发了控制系统.实验结果表明：该DC-DC变换器具有输入电压范围广、输出电压精度高以及良好的动态、稳态特性
Abstract:
The electrical energy from solar photovoltaic array is influenced by solar light intensity and environmental factor and has strong randomness,instability and gap characteristics.A DC-DC converter having wide input voltage,output voltage and high precision was designed in this paper.A non -isolated Buck/Boost topology was used as the main circuit of DC-DC converter,the parameters of the circuit were given and a control algorithm was proposed based on voltage,current double closed loop.The system took the high-speed high-performance micro processor TMS 320F28335 as the control core to develop its control system.The experimental results showed that the DC-DC converter had a wide input voltage range, a high output voltage precision and the good dynamic and steady-state characteristics.
