Hello, I am designing a Half-Bridge LLC Converter to step down voltage from 420V to 24V trying to get at least 95% in efficiency. I'm a Second year Engineering student and I am doing this for a Student Design team. I am going over Youtube watching tutorials and trying to find more resources on how LLC Converters work and what formulas are uses. I made an LTSpice model to understand some of the basics, but I am a little lost.

What are the key steps I should take in terms of initial design decisions, simulations, and trade-off analysis. I have Altium and PCB Design Experience, but no Power Electronics design.

Thanks!
