Are you able to share any information about the sourcing or construction of the transformer used in the 60kW Dual Active Bridge reference designs CRD60DD12N-GMA and CRD60DD12N-GMB?

    Hello anehring,

    The transformer was a custom solution that we wound internally with a magnetizing inductance of ~100uH and a leakage inductance of ~5uH. It used Ferroxcube E100/60/28-3C94 ferrite E cores with AWG4-equivalent Litz wire. We’re actively working with our magnetics partners to develop a transformer solution for public release.

    Thanks,

    Chris N.

    Hi Chris,

    Thanks for the information! Pointing me towards a core is very helpful, looking forward to the public release transformer as well.

    Thanks,

    Andrew
