Resonant Tank Values

- High inductance ratio minimizes primary magnetizing current.
- A relatively large Cr means substantial power headroom and a relatively small capacitor ripple, making capacitor ESR losses less of an issue.
- Using FHA, an LLC tank with 50% margin is derived to be Cr = 100 nF, Lr = 20 μH, Lm = 180 μH.
- In this webinar we will focus on the magnetics design and analysis. For more details on the LLC design choices, and selection of other components such as semicondutors, please refer to the cited Application Note and PE Seminar.
