基于Matlab的大功率电源控制器设计仿真

摘要

对电源控制器进行建模仿真可为系统的设计分析提供重要的指导作用.针对20 kW电源控制器,设计了全调节母线的模块化系统方案.基于Matlab/Simulink软件,构建了包含顺序开关分流调节器、蓄电池充放电调节器的仿真系统.通过设置合适的电路参数及控制参数,仿真系统可准确模拟多种工况下电源控制器母线的动静态响应.仿真结果表明设计的电源控制器能够满足20 kW负载的供电需求.%Modeling and simulation play an important role on the design and analysis of the high-power power conditioning unit.For the 20 kW power conditioning unit,a modular system with a full regulated main-bus was designed.Using the Matlab/Simulink software,a simulation system was established,which contained sequential switching shunt regulators and battery charge/discharge regulators.With appropriate circuit parameters and control parameters,steady and dynamic responses of main-bus were simulated under various working conditions.Simulation results show that the designed power conditioning unit can meet the requirement of the 20 kW payload.
