摘要: 为了简化三电平逆变器控制算法、提高系统稳定性,提出通过交替使用不同空间电压矢量以实现磁链跟踪控制的二极管箝位型三电平逆变器SVPWM控制算法.依据Matlab/Simulink的仿真结果,进行以TMS320F2812 DSP为控制核心的三电平逆变器整机试验.结果表明,SVPWM算法简单,易于掌握,二极管箝位型三电平逆变器输出电压经滤波后十分接近正弦波,且系统稳定性较高,能够较好地满足工程需要.

Abstract: In order to simplify the control algorithm of three level inverter and improve the stability of the system, diode clamped three level inverter SVPWM control algorithm was put forward which based on the change of the space voltage vector to realize magnetic chain tracking control.By Matlab/Simulink simulattion output, the machine testing was made with TMS320F2812 DSP as the control core of diode clamped three level inverter.The results showed that SVPWM algorithm was simple and easy to master, the output voltage of diode clamped three level inverter was close to sine wave, the system had better stability to better meet the needs of engineering.-
