Homebrewing your own high amp controller is fraught with frustration, anger, and anguish. In the end you will end up buying a commercial product anyway. If you do go the homebrew route, at least use integrated bridge chips made for automotive applications instead of the discrete route. The chip sets have nice features like current/ temp sensing and limiting.
Infineon and Motorala make some nice half and full bridge chips. One example is the Infineon BTS7960B or similar. Here's a simple h-bridge using the BTS7960B that can be easily driven by a microcontroller. - http://www.robotpower.com/products/simple-h_info.html Steve Tyng On May 5, 7:59 pm, Loren <[email protected]> wrote: > Both, really.
