I found these with a Google search for "High Power H Bridge Circuits":

Hi,

I found this chip (VNH2SP30) used by robot hobbyists. It's an H-bridge originally used in cars to driver power windows and the like. It's rated at 30A burst and about 14A continuous with no heat sink. Pololu sells carrier boards if you don't want to do surface mount. I bought some from Digikey for about $15 (CAD).
