Splitting Inductance Tuning Method to Eliminate High Frequency Oscillation in Dual Active Bridge Converter
There is a growing trend towards operating higher frequency in dual active bridge (DAB) converters to achieve higher power density. At the meantime, the high frequency oscillation (HFO) problem introduced by the parasitic components of the transformer and high dvldt of the ac link excitation voltage becomes detrimental.
Matching the oscillation frequency with the zero crossing points (ZCP) of the DAB dvldt excitation has been proven effective to eliminate the HFO problem. In this paper, a splitting inductance tuning method is proposed to adjust the circuit frequency characteristic and place the lowest impedance path at the ZCP frequency, thus eliminating the HFO.
Theoretical analysis is given along with the experimental results from a 1 MHz Gallium Nitride (GaN) based DAB converter prototype.
