Abstract
A switching tube control method and device, and a direct-current converter. In the solution, after a switching tube on a leading bridge arm in a phase-shifted full-bridge converter is disconnected and a current on a transformer is not greater than a current preset value, a corresponding switching tube on a lagging bridge arm is controlled to be disconnected, and it is ensured that the current flowing through the switching tube is small when the switching tube on the lagging bridge arm is disconnected, such that the soft turn-off of the switching tube on the lagging bridge arm is realized, the loss is reduced, the anti-interference capability of the switching tube is improved, and the EMS performance of the switching tube is improved.
