摘要
提出了一种新型等脉宽移相叠加阶梯波控制方法,设计了H桥二重化三电平的大功率发射机功放电路模型,利用Matlab软件进行建模和仿真,证明该控制方法简单合理,能减小发射机输出的高次谐波含量,且易于电路实现。最后进行了模拟试验,证明仿真起到了指导实践的目的。
A new phase of equal pulse width phase-shifting and plus synthesis superimposed wave control method is introduced.The H-bridge duplicate three-level power magnifying circuit model of the large power transmitter is de- sigued.Using the Matlab software for modeling and simulation to verify the control method is simple and feasible.The circuit can be realized easily and the high harmonic content of the output voltage of transmitter can be reduced.In the end, the method plays a role in guiding practice which is verified by the simulation in the laboratory.
