H-Bridge with High Current Transistors

hi all,

  searched on google many types of h-bridge(hb) of them low current circuits,
as know h-bridge control dc motor in 2 ways, i'd if can give me type of transistor able
handle high current like  12v 24v , 5a 10a, @ least i'm gonna use 19v 4.7a power supply control dc motor.

   and 1 more question, how i'm able control 2x dc motors same h-bridge in same time , in
opposite directions, or should build (hb) each motor ? if need 2 hb each motor i'm able @ least control
the 2 motors diferent hb in same time , opposite directions same arduino ?


thanks, hope reply (noone lately reply me).  =(

if have ask these questions, suspect going have great difficulties when try implement yourself.  h-bridge way go, there many practical issues not prepared handle.  have not specified n-fet, p-fet, igbt, npn bipolar, or pnp bipolar.   these types of transistors used in h-bridge.  prepared deal issues such shoot-through?  suggest purchase ready-made h-bridge motor driver.

you need 1 h-bridge per motor.  each h-bridge require @ leat 2 outputs arduino.  more 2 outputs needed, depending upon functionality of h-bridge.  example, want able perform braking well?

you justed posted today.  responses on forum unpaid.  should expect wai 0, 1, or 2 days responses here.

good luck!
