摘要

简要阐述了双极性SHEPWM（特定次消谐脉宽调制）的数学模型，建立了消除特定谐波的非线性超越方程组，论述了求解此非线性超越方程组的新方法，推导了开关角计算关键参数。针对内燃机车主变流器主电路特点，进行了基于TMS320F28335 芯片+FPGA 的控制电路的硬件和编程设计。试验结果表明，在不同开关角之间切换时过渡处未出现电流波动，切换较平稳。

Abstract

Mathematic model of ambipolar selected harmonic elimination PWM was explained briefly. The nonlinear surmounting equations of eliminating the specified harmonic were provided, and the new resolving methods for these equations were discussed, and the key parameter of switch angle was deduced. Application of SHEPWM in diesel locomotive traction converter was studied emphatically, and design of control hardware and programming based on TMS320C28335 and FPGA chip was realized. The experimental results showed the stable switching course of different switch angle without current impulse.
