Design and Simulation for Mine DC-traction Rectifier Based on Sliding-mode Control

针对单相全桥PWM整流电路,详细分析了其电路特点和工作原理,在此基础上,建立了单相电压型PWM整流器的数学模型。提出基于滑模变结构控制的煤矿直流牵引PWM整流器,并在MATLAB/SIMULINK中进行仿真,给出了仿真波形。

The theory and characteristics of the single-phase full-bridge PWM rectifier circuit are elaborately analysed,on this basis,the mathematical model of a single-phase voltage-type PWM rectifier is established.A mine DC-traction PWM rectifier which based on sliding mode control is proposed.The simulation in MATLAB/SIMULINK gives the simulation wave-form.
