论述了一种用于航空发电机测试用的三相馈能式电子负载功率拓扑方案及其电流控制策略。首次将三相馈能式拓扑方案应用于航空发电机测试负载，这种馈能式电子负载采用电流滞环PWM技术，可实现功率因数无级调节，既可模拟阻性、容性、感性等各种航空发电机负载形式，又能通过三相逆变器将发电机发出的电能以功率因数1回馈给电网，这样降低了设备的功耗，缩小了设备的体积。建立了系统d-q模型。对系统方案进行了理论论证。并给出了Matlab仿真结果。

Study on Simulation of Three-Phase Energy-Feedback Type Electronic Load Based on Current Hysteresis Loop Control

Discussing a kind of power topological solution and its current control method of the three-phase energy feedback type electronic power load used in aero-generator testing. The three-phase energy feedback type circuit topology is applied to the load testing of aero-generator for the first time. The current hysteresis loop PWM control technology is used in this kind of electronic load so that it could realize the smooth adjustment of power factor,which means it could simulate all kinds of load forms in aero-generators such as resistance capacity and inductor. In addition,the load could send the power generated by the aero-generator to the utility power system with unit power factor,which reduces the power loss of the system and the size of the equipment. In this paper the author has built the d-q mathematical model of the system and given the simulation result of Matlab.
