So when my smps circuit have 2kw of mosfets but I can only get 800 watt from the 2kw of mosfet at 225khz and the main voltage only drop 3 voltage and the input current is 12amp 133 volt and am losing 1200 watt how is this even possible to have 60 percent losses
It is very nice explanation on all calculation and useful. do you have a template to do all calculations by inputs all necessary parameters? I like to get a copy if possible

For lower frequency operation Rds(on) isn't necessarily the cause of dissipating the most power - the capacitance can be responsible for up to 300% more power loss.
4:17 When the device is turned off, does voltage rise because something is building up on one side of the switch? Or something is emptying out on the other side? Or neither? Or both?
Very interesting videos. Maybe you can help me with this. I am having issues selecting the right diode for a full wave rectifier because the datasheets do not include the Repetitive Peak Forward Surge Current (IFRM) for the diodes. Is this parameter related to the Average Forward Current provided in the datasheet? For what I understand, the current peak in the diodes during the charging time of the capacitors must be lower than the I FRM. Am I right? or in reality it should be lower than the Non-repetitive Peak Forward Surge Current (IFSM)? Thank you in advance
