The Impact of Periodic Variable Switching Frequency Modulation on Power Transmission in Dual-Active-Bridge Converter and an Improved Scheme

IEEE transactions on power electronics, 2023
Variable switching frequency modulation (VSFM) is an effective means to suppress electromagnetic interference (EMI). It disperses the energy of narrow-band harmonic to a wider spectrum range, so that the EMI spikes can be attenuated. However, the current

Mitigation of Current Ringing Effects in a Dual Active Bridge Converter

2023 IEEE 32nd International Symposium on Industrial Electronics (ISIE), 2023
The mitigation of the ringing effects on a dual active bridge (DAB) converter by implementing a planar transformer has been investigated. Specifically, the consequences associated with the stray capacitances of planar transformers have been analysed and modelled, referring to a specific case study. The analysis of input and output impedances shows that
