And what is the standard for calculating this IRFP250 Vds = 24 V Id = Max 4 A Vgs=15v Ferq = 10 KHZ Driver = IR2104 Many thanks

It´s the current flow and the impedance...that may cause error voltage. Easiest way: --> use a proper GND plane (one layer just for GND, no other signals) and use decoupling capacitors. Klaus

Klaus Click to expand... thank you but i want what is the standard for calculating this distance for reduce the error voltage effect
