摘要
建立了基于开关函数的电压型四象限变流器数学模型,结合瞬态电流控制,搭建了整个基于开关函数的四象限变流器及控制系统的仿真模型,并在MATLAB环境下进行了稳态及动态的仿真,验证了瞬态电流控制是一种较好的控制等路。
The mathematic model of voltage-source four-quadrant converter was built based on switching function,and with the transient current control method,the simulating model of converter and control system was established.Steady-state and dynamic simulation in MATLAB was carried out,validating the effect of control scheme.
