摘　　要：将具有谐波小、直流电压利用率高、算法简单、规律性强、易于数字化实现特点的电压空间矢量脉宽调制(SVPWM)技术应用到高效节能的内馈斩波串级调速系统中。首先从三相电压型有源逆变器和SVPWM控制技术的基本原理出发,建立基于SVPWM技术的有源逆变控制结构图,利用SIMULINK动态仿真工具实现了SVPWM控制算法在有源逆变的动态仿真。在此基础上搭建硬件实验平台,通过实验的手段证明了将SVPWM技术应用到内馈串级调速系统中的可行性。The SVPWM control technology which have little harmonic,high utilization rate of DC voltage,strong regularity and easy-to-digital realization was applied to the inner-feeding chopper cascade speed regulation system of high efficiency energy-saving features.From the three-phase voltage-type inverter and the basic principle of SVPWM control technology,the overall structure of the three-phase active inverter control was built which based on SVPWM control strategy and used SIMULINK dynamic simulation tool to achieve the simulation of SVPWM control algorithm for the active inverters.Based on this simulation results,the hardware experimental platform is built to prove the feasibility of applying the SVPWM technique to the inner-feeding chopper cascade speed regulation system.
