Hi Guys,
I asked before about H-Bridge Mosfets.
Currently My circuit is working prety good, see at:
YouTube - roeebloch's Channel
I have 2 x N-CH and 2 x Pch
The N-ch is driven directly through Pic output (through 47 ohm resistor)
My P-CH is driven through PushPull
I have 2 x PWM signals and 2 x '0' or '1' logic
But I have noticed something strange:
1.IF I connect my PWM to N-CH and P-CH to logic my Power boards gets very hot after 5 minuets of driving but my system is very stable (the segway is balanced good)
2. If I connect my PWM to P-ch and logic to N-CH the system is working, not very stable, but Mosfets do not get a lot of heat even after few minuets of driving.
Does any one have any idea why this is happening?
Thanks,
Roee.
