摘要
针对动车组、机车车载单相逆变器效率较低且控制粗放的问题,提出了一种针对两级式逆变器的功率前馈寻优控制方法。该方法综合了变步长母线电压寻优和前馈控制理念,可有效提高逆变器的工作效率,最后通过试验证明所提方案的有效性和正确性。
To solve the problem of low efficiency and extensive control of single-phase inverter on EMU and locomotive,a power feed-forward optimization control method for two-stage inverter is proposed.This method combines the idea of variable step size bus voltage optimization and feedforward control,which can effectively improve the working efficiency of the inverter,and the effectiveness and correctness of the proposed scheme are proved by experiments.
