I have a CLLC circuit in which I am trying to find values of the inductors and capacitors. I know the circuit needs a gain of at least 10 dB at 50kHz and below 1 db at around 30-40KHz. This has to be true while varying the load. I have set up the circuit in ltspice where I am using the .step function to sweep through component values and am looking at the bode plots.
The problem is I have so many graphs on the screen that I cannot keep track of them all. In the 1000s. Is there a way I can only display the simulations which have over 10dB at 50KHz and under 1db below 30Khz? Basically I want to get rid of all the sims that don't meet my criteria. The circuit is way too complex for me to solve mathematical.
It's for a tank in a resonant tank charger. The load will vary from 4ohm to 12homs. The circuit is bidirectional and it would be helpful if the transfer function is similar in both directions. What other info should I post? I've been trying to make something similar to the circuit in this article. https://www.researchgate.net/profile/Ho_Sung_Kim3/publication/260496284_Design_Methodology_of_Bidirectional_CLLC_Resonant_Converter_for_High-Frequency_Isolation_of_DC_Distribution_Systems/links/00b7d5347ada7c098b000000/Design-Methodology-of-Bidirectional-CLLC-Resonant-Converter-for-High-Frequency-Isolation-of-DC-Distribution-Systems.pdf I understand basic laplace transforms but not enough to put this all together yet. I'm not overly interested in high efficiency, I know the load varies by a lot.
