Abstract

The invention relates to a DC transformer and a control method thereof. The control method of the DC transformer adjusts the original input voltage value according to the input voltage offset, so that the output voltage value of the DC transformer can be kept stable, and the voltage stability of the output DC power can be improved. At the same time, the control method is to control the input voltage value of the DC transformer unit. At this time, regardless of whether the input side of the DC transformer is in an active state or a passive state, the voltage at the input terminal can be maintained stable, so that the output voltage value remains constant. Stablize.

Description

technical field [0001] The invention relates to the technical field of DC voltage conversion, in particular to a DC transformer and a control method thereof. Background technique [0002] The DC transformer with input in series and output in parallel can be used for voltage conversion of DC. The input terminal of the DC transformer can be connected with the DC bus, and the voltage conversion of the DC power can be realized through the electromagnetic induction of the primary coil and the secondary coil. [0003] In traditional technology, a DC transformer usually realizes voltage conversion through electromagnetic induction and directly outputs DC power. [0004] During the process of realizing the traditional technology, the applicant found that the voltage stability of the output direct current of the traditional direct current transformer is poor. Contents of the invention [0005] Based on this, it is necessary to provide a DC transformer and a control method thereof...
