TIDA-020031: Shim inductance calculation

Part Number: TIDA-020031

Could you please provide complete calculation for the below equation. The picture below is from the design guide and it does not tell what Ip_off is.

    Hi Aneesh,

    Ip_off is the primary side current when lag bridge is switching off. You should define the load percentage Coef to achieve ZVS.

    Then Ip_off can be approximately calculated by Ip_off = (Coef*Iout+ΔIL/2)/(2*nps).

    nps is the turn ratio, Iout is the rated output current, and ΔIL is the ripple on output choke.

    Best Regards
