Abstract

Buck-Boost Converter with Coupled-Inductor (BBCCI) can be utilized to equivalent the DC-input source-voltage with the load-voltage. Current mode-regulator can be utilized to synchronize the output-voltage of the BBCCI system. Modeling and regulation of BBCCI becomes an important issue. This paper deals with modeling and simulation of closed-loop BBCCI system through current mode-regulator using MATLAB. The goal of this work is to enhance the lively response of the closed-loop BBCCI system utilizing current mode regulation. The closed-loop controlled BBCCI systems with voltage mode and current modes are modeled, simulated and the outcomes are analyzed. The outcomes denote that the lively response is improved using CM controller. The recommended system has benefits like low THD, low settling-time and steady-state error. The hardware is fabricated and tested. The experimental results match with the simulation results of BBCCI.

采用减小电流纹波耦合电感的电流模式控制PV降压升压变换器系统

带耦合电感的Buck-Boost变换器(BBCCI)可以将直流输入源电压与负载电压等效。电流模式调节器可用于同步BBCCI系统的输出电压。BBCCI的建模和调控成为一个重要的问题。本文利用MATLAB对电流模式调节器的闭环BBCCI系统进行了建模和仿真。这项工作的目的是利用电流模式调节来增强闭环BBCCI系统的动态响应。对具有电压模式和电流模式的闭环控制BBCCI系统进行了建模和仿真，并对结果进行了分析。结果表明，采用CM控制器可以改善系统的动态响应。所推荐的系统具有THD低、沉降时间短、稳态误差小等优点。硬件制造和测试。实验结果与BBCCI的仿真结果吻合。
