Re http://forum.allaboutcircuits.com/newreply.php?do=newreply&p=576567Try to understand how the bootstrap capacitor is charged. I think it is pretty much well explained in the link I sent.
Old Post, but does this confirm that in a MOSFET full bridge the upper FET can be kept on and the bottom switched for recharging VB?
I get conflicting stories!
Also lower and opposite upper cannot be kept on 100%, due to no VB generated?
Max.
