摘　　要：基于滞环控制理论,提出了一种简便易行、易于应用普及的三相四线制AC/DC双向变流系统的主电气及控制回路设计方法。通过Matlab仿真软件,进行了一定功率条件下的整流与有源逆变双向充放电电压、电流波形仿真,验证了主电气拓扑设计及控制方法的有效性。需要说明的是,本系统在对网侧交变电流进行直接跟踪反馈控制中,通过谐波源抑制技术使得网侧电流波形更加趋近于标准正弦波,从根本上减少了网侧谐波次数,从而提高了电能质量。Based on hysteresis control theory,the paper puts forward a design method of main circuit and control loop for three-phase four-wire bi-direction AC/DC converter,which is simple ＆ easy to popularize ＆ apply,and also makes a simulation of voltage and current waves in bi-directional charge and discharge with controlled rectifier and active inverter under the condition of a certain power by using Matlab.The results verify the availability of the topology design of the main circuit and control method.In particular,the system adopts direct-current tracking feedback control strategy for grid alternating current,to make the grid current waveform approach to standard sine wave by using the suppression technology of harnonic source,ensuring higher power quality with less harmonic interference.
