摘要
级联多电平拓扑结构广泛用于高压变频调速、无功补偿以及电气化铁路牵引等众多领域,本文对基于此类拓扑结构的载波水平移相SPWM调制控制技术进行了Matlab仿真分析,验证了载波水平移相SPWM调制方法的可行性以及理论分析的正确性。在此基础上应用FPGA器件及其开发环境通过软件编程实现载波水平移相SPWM波形生成,进而设计了三相级联载波水平移相SPWM控制器,并通过代码仿真验证了本方案的可行性。
Cascade multilevel topology is widely used in high voltage variable frequency speed regulation, reactive power compensation and electrified railway traction etc. This paper on such topological of the carrier level phase-shift SPWM modulation control technology based on Matlab simulation analysis, which verifies the feasibility and correctness of the theoretical analysis of the carrier wave SPWM modulation method. On the basis of the application of FPGA device and its development environment through software programming to realize the level of carrier phase shifting SPWM waveform generation, then design the three-phase cascade level of carrier phase shifting SPWM controller, The feasibility of this scheme is verified through code simulation.
