摘　　要：针对传统能耗型带载测试造成能源浪费,负载形式无法灵活调节,设计的直流能馈型单相交流电力电子负载(Power Electronic Load,PEL)能够灵活模拟各特性负载,能量直流直接回馈至待测逆变电源直流输入侧,达到能源二次利用的目的,提高能源的利用率。首先介绍直流能馈型单相交流PEL的拓扑结构,然后将无源控制策略引入到具有非线性特性的负载模拟单元,设计无源控制器,以获得更好的动态性能,减小静态误差,使负载模拟调节更加方便;能量回馈单元采用双环PI控制,实现能源循环利用。最后搭建了Matlab/Simulink仿真模型和基于TMS320F28335样机系统,仿真和实验结果表明了所采用控制策略的可行性。In view of the energy waste caused by the traditional energy consumption type Load test,the Load form cannot be adjusted flexibly;the designed DC energy feed-type single-phase AC Power Electronic Load(PEL)can flexibly simulate the Load characteristics;the energy is directly fed back to the DC input side of the inverter to be tested,to achieve the purpose of secondary energy utilization.Improve energy efficiency.In this paper,the topological structure of dc energy fed single-phase AC PEL is firstly introduced,and then the passive control strategy is introduced into the load simulation unit with nonlinear characteristics.The passive controller is designed to make the DC energy fed single-phase AC PEL get better dynamic performance,reduce the static error,and make the load simulation and adjustment more convenient.The energy feedback unit adopts double loop PI control to realize energy recycling.Finally,the Matlab/Simulink simulation model and the prototype system based on TMS320F28335 are built.The simulation and experimental results show the feasibility of the control strategy adopted.
