Hello

I have built a pwm controller using a PIC.

I would now like to build a circuit that will actually drive a 10 amp 12V DC motor.

I am hoping to use the microcontroller but do not understand how to drive the high currents.

Perhaps some one could give me a pointer as to what direction I should look

Thanks
 
If you want it to run in both directions you need what is called an H-Bridge. If you only wnat it to go in one direction it is easier.
Is 10 amps the running current or the maximum current?
 
This isn't too bad for a newbie: https://www.electro-tech-online.com/custompdfs/2012/11/h-bridge.pdf

Then Google the suggested examples e.g. "xxx Datasheet"

In simple terms, there are IC's called an H-bridge which can allow coasting, braking, forward and reverse.

The PDF shows four switches. These are usually transistors or MOSFETS.

A very simple H-bridge has a direction and a NOT Enable signal. Not ENABLE is driven by PWM for speed.
