Abstract

Dual Active Bridge (DAB) bi-directional DC-DC converters can transmit power in both directions, realize zero voltage switching (ZVS), and have high power density, which can be well applied to power electronic transformers. Three common control methods for DAB converters are described in detail in this paper. They are phase-shift control, single PWM, and dual PWM control. Aiming at the shortcomings of large loop current and limited range of zero-voltage switching when the converter has low-load operation, a multi-mode control is proposed, which broadens the range of zero-voltage switching, reduces the effective value and peak value of the current, and makes converter efficiency improve. Finally, MATLAB software was used to simulate the feasibility of the program.
