Application of Random PWM Technology in DAB Converter
2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018For dual-active-bridge (DAB) DC/DC converter, when conventional pulse width modulation (PWM) is used, large harmonics are generated at the switching frequency and frequency multiplication, resulting in conductive electromagnetic interference (EMI). The random PWM technology can improve the electromagnetic compatibility of the system by dispersing the ...

Paralleling of DAB converter using the gyrator theory
2013 Brazilian Power Electronics Conference, 2013This work presents mathematical analysis, simulations and experimental results of the parallel connection of DAB converters. The gyrator technique is used to model the DAB converter and to determine a simple equivalent circuit. As the DAB converter is a natural gyrator, the paralleling can be easily done, and the control logic is simplified.
