Cayenne connected Dual "H" Bridge Motor Controller


#1

An “H-Bridge” is a bi-directional motor controller-
Used (for example) up/down, open/close, forward/reverse motors…
and it CAN be used with PWM motor speed controllers!

TIP120 transistors are pretty big, a TO-220-3 package,
and this circuit WILL be needing heat sinks
to dissipate up to 100 watts (up to 8 Amps @ 12 volts), so…
I have a design challenge on my hands.

…working on it…
