At the same time, the detailed description and analysis of the structure of the pulse converter and the inverter of CRH2 are introduced. The paper also compares the advantages and disadvantages of the tri-level pulse rectifier and the carrier phase shift multi-pulse. Through considering the control strategy of CRH2’s and CRH5’s DC link and the inverter control method in detail and ex- plaining the differences in different aspects, the conclusion is drawn. CRH2, CRH5 and CRH380A adjust the inverter frequency through the inverter control software, so that the product of voltage and time of the inverter’s output voltage can be equal in the positive and negative cycle to elimi- nate the influence of the second harmonic voltage. While the CRH3 and CRH380B set the second harmonic absorption circuit, the LC se
