      To wrap up the mosfet h-bridge designs, I have posted the three most interesting circuits in the file section. All feature very low voltage drop, forward, reverse, brake and freewheel mode. 
       
       
      The mosfets are chosen for the required current and voltage rating  typically up to 10A and 18V.  A suitable automotive type fuse in series with the +V supply should be used to protect against  short circuits. The next generation of these circuits will include a novel current limiting scheme. These h-bridges should cost between $5 and $10 to build from scratch. 
       
      enjoy
