When the current method is used to control the DC transformer of the DC-DC converter, the control efficiency is low, the immunity is poor, and the loss detection error is large. In order to solve the existing problems, a DC transformer control method based on the SRDAB DC-DC converter was proposed. By analyzing the transient losses of semiconductor devices, the on-state losses of semiconductor devices, the general losses of transformers and other losses generated during the operation of the DC-DC converter based on the series resonant dual active bridge (SRDAB), the total loss in the working process of the converter was calculated. Taking the minimum loss as the goal, the DC transformer control model of the converter was established, and the relevant constraints were set, and the genetic algorithm was used to solve the DC transformer control model to complete the control of the DC transformer. The experimental result shows that the proposed method has high efficiency, good immunity, small loss detection error and good practical application effect. [ABSTRACT FROM AUTHOR] |
