| Abstract: | According to the theory of PWM and in order to m eet the IEEE- 5 19recomm endation standard,the optim al output waveform of high- voltage converter is discussed in detail.This paper puts forward two control strategies to get optimized output waveform ,i.e. tim e- division control and phase- offset control. Especially,how to get control regulation is discussed also when the output frequency and m agnitude vary.At the sam e time,this paper gives the sim ulation waveforms for two types of comm on- m ode voltage rectifier comm on- m ode and inverter comm on- m ode ,and analyses the dynamic characteristics of power system for two control strategies. |
