Abstract

This paper deals with adjusting the current controller of a boost DC-DC converter employed within the structure of a load simulator. We use the simulator to perform ground testing for a number of power supplies that involve renewables (solar cells, wind generators, etc.). The simulator generates DC current waveforms of various shapes. The DC current range is within 0…220 A. We use the current of 180 A as the reference value of the load current. The aim of this paper is to investigate a method of optimal controller adjustment for the boost DC-DC converter. We employed the magnitude optimum to fine-tune the controller. A simulation model of the boost converter was built in Matlab Simulink and the designed current controller options were implemented. The modeling results in the form of dynamic current and voltage waveforms were analyzed. The proposed technique of the current controller tuning proved to be valid. The performance indicators meet the requirements applied to the load simulators of power supplies.

基于升压DC-DC变换器的负载模拟器电流控制器的调整

本文讨论了负载模拟器结构中升压DC-DC变换器的电流控制器的调整问题。我们使用模拟器对一些涉及可再生能源(太阳能电池，风力发电机等)的电源进行地面测试。该模拟器可生成各种形状的直流电流波形。直流电流范围为0 ~ 220 A。我们用180a的电流作为负载电流的参考值。本文的目的是研究升压DC-DC变换器的最优控制器调整方法。我们采用最优幅度对控制器进行微调。在Matlab Simulink中建立了升压变换器的仿真模型，并实现了所设计的电流控制器选项。并对动态电流和电压波形的建模结果进行了分析。所提出的电流控制器整定技术是有效的。性能指标满足电源负载模拟器的要求。
