摘要
双级矩阵变换器是在传统9开关矩阵变换器的基础上发展起来的一种新型矩阵式变换器,其自身的优点更适宜作为变速恒频风力发电系统中双馈电机的励磁装置。分析了双级矩阵变换器的拓朴结构和基本原理,根据其特点采用PWM控制与空间矢量调制法相结合并应用零电流换流法进行控制,并基于Matlab/Simulink对双级矩阵变换器进行了建模与仿真。仿真结果验证了控制方案的可行性和正确性。
Two - Stage Matrix Converter （TSMC） is a kind of new matrix converter developed on the basis of the conventional nine- switch matrix converter, by virtue of its advantages, more suitable for serving as the exciter of variable speed constant frequency doubly- fed wind power generation system. The topology structure and principle of TSMC are analysed, and taking accordingly the PWM space vector modulation and zero current commutation to research its features. A simulation mo - del based on Matlab/Simulink is built for the TSMC,and the simulation confirmed the feasibility and validity of control scheme.
