yes, i find it hard to design it.That is a horrible H-bridge.

when designing this in PCB, i use the same schema? or there are things i should change in (i think the output of the circuit should not be in the middle)? and which program is easier to do this task? is Proteus good for this?The one I use regularly is this one... I know it doesn't use FET's but it works well for me..

Its safe ( no shoot through ) easy to use... PWM on the ENA* line..
I use Proteus for everything... All my boards have been done with Ares....when designing this in PCB, i use the same schema? or there are things i should change in (i think the output of the circuit should not be in the middle)? and which program is easier to do this task? is Proteus good for this?
i couldn't find irf4905 and irfz44n (which i have, and want to use in the circuit) in ProteusI use Proteus for everything... All my boards have been done with Ares....
For making PCB you only need the To220 package.. However... Both of those devices are in Proteus..i couldn't find irf4905 and irfz44n (which i have, and want to use in the circuit) in Proteus
edit1: is '4n35' the same as cnx35 in Proteus?For making PCB you only need the To220 package.. However... Both of those devices are in Proteus..
No... Not by a long way...that's what i managed to do, is the circuit design correct? and how to optimize this PCB?
thank you, i'll try this circuit and tell you if it works.No... Not by a long way...

But I still not happy with this design... It needs a big cap and resistors on the optocoulers... Also I would have thought, 100r on the gates..???? Someone else will know.
