TIDA-010054: DC blocking capacitor

TIDA-010054: TIDA-010054: DC blocking capacitor

Hello,

Regarding the design of the DC-blocking capacitors, I am interested in why it is so crucial to maintain the rectangle waveform on the leakage inductance in the DAB.

Thank you.

    Hi Milan,

    Thanks for reaching out. 
    The design of TIDA-010054 is based on the rectangular waveforms applied to the coupling/leakage inductor. Changing this impacts the control scheme as well as the maximum power transfer and would require a different theoretical derivation.
    In our design we wanted to keep the approach of a standard Dual Active Bridge with phase shift control of rectangular waveforms.

    Best regards,

    Andreas
