Hi everyone. I have three separate questions but linked each other. 1 - A Mosfet is a bidirectional device and from what I know, this happens because of the presence of an intrinsic diode (body diode) that exists due t… --- ## [How can i calculate switching losses and efficiency?](https://forum.plexim.com/t/how-can-i-calculate-switching-losses-and-efficiency/650)
