双SVPWM三电平变流器电机控制特性研究

Motor Control Characteristic and Research on Three Level Converter Based on Double SVPWM

在分析SVPWM调制方式及中点电压不平衡调制策略的基础上,建立双SVPWM三电平AC-DC-AC变流器电机控制系统。分析电机运行特性,实现能量四象限流动。在Simulink环境中仿真测试,分析在突加负载工况下电机运行特性,验证了变流器系统的正确性。

The structure and working constructed the dual three-level SVPWM AC - DC pie of three-phase converter transmission is introduced. It is AC converter motor control system on the base of the analysis on SVPWM modulation mode and midpoint voltage unbalance strategy. It is analyzed the motor operating characteristics and achieved energy four-quadrant flow, and carried out in the Simulink. Working at impact load, verify the correctness of the system.
