摘要

高增益直流-直流转换器备受研究人员的关注。但有人担心,高增益转换器的效率较低,开关应力较大。该转换器拓扑结构包括两个准阻抗源网络和一个电压倍增器单元,以实现非常高增益的输出电压。通过采用扰动和观测最大功率点跟踪机制,可减轻因光伏辐照变化而产生的输入变化。工作的仿真在 MATLAB/ Simulink 中实现,硬件电路则使用 dsPIC30F2010 控制器进行了验证。关键字高增益 DC-DC 转换器、非线性载波控制器、电压调节、扰动和观测最大功率点跟踪、太阳能光伏发电

High Gain DC-DC Converter for Photovoltaic System
The, high-gain DC–DC converters dragged much attention among the researchers. But there is a concern that high-gain converters have less efficiency and high switching stresses. The converter topology has two quasi-impedance source network and a voltage multiplier cell unit to facilitate very high-gain output voltage. The input variations due to varying irradiation of photovoltaic are alleviated by employing the perturb and observe maximum power point tracking mechanism. The simulation of the work is realized in MATLAB/ Simulink arena, and hardware circuits are validated using the dsPIC30F2010 controller. Key Words: High-gain DC–DC converter, non-linear carrier controller, voltage regulation, perturb and observe maximum power point tracking, solar photovoltaic
