LTSPICE Soft Switching Buck (Theory + Simulation)

[@Hyo9000]

Thank you, this is so good!

this configuraton is for zcs right? For the zvs the capacitance will be placed in parallel to the switch? In terms of efficiency what are the differences between zcs and zvs?

am trying to calculate a value for my own Lr and Cr but i dont know how to get i2 would you mind giving me a hint

Consult Fundamentals of Power Electronics pdf online , chapter Soft Switching cells to have the complete theory and formulas

​@@manoA98A gave it a go the result is okay but unlike yours my nmos current drops below zero. do you have any idea why

[@manoA98A]

@@Jeff-wf1ww It's normal, check also the Switching waveform of soft Switching under all conditions and you Will find that It can start from negative current and then proceed with like a sine
