Thank you so much. Help me a lot!

LTSpice is one of the easiest tool for circuit simulation. And it is very powerful. You can learn it just by doing. In the beginning you can just click some very simple circuits together in order to get familiar with the look and feel. To get progress is just a question of a few weeks using it.

Very useful, thank you for sharing.

Thank you

how do you copy the test pin to measure voltage around the inductor

[@rajenmondal007]

superb.....just like a boom. thanks sir

[@gkdresden]

With respect to the component selection. You usually have a feeling about the voltages and currents for the components to handle. So if you expect to get 25 V at 1 Ohm you will expect to get 25 A of current to handle for the active devices. So you will select devices which can handle 60 to 100 V and 30 to 50 A. You will not use a 1 A diode in this circuit as you have shown.

Hi, Can you tell me how to simulate the constant current source wiht the buck converter in LTspice. Thank you.

[@khushishenoy31]

Can u pls do using transistor

[@TechSouls-wn6jc]

how to find output power using ltspice and input power for buck and boost converter

[@charanreddyakula5383]

In LTspice plot section you can write something like V3*I2( identity the nodes or name them as you want) and it plots power
