View H Bridge Mosfet Driver Images. Now i have understood that i have problem with driving high side mosfets as their gate. It is just as easy to use combinations of mosfets.

My motor drive and my power supply voltage is 12v.
The reason we want to have a driver is because there is the highside mosfet, which is m1 and m3 from the circuit above, do not have sufficient vgs value to turn on fully, therefore it cannot deliver full power to. I have used mosfets in h bridge designing for pure sine wave inverter. The test with 5v to controll inputs, to change the directions. The mosfet gates are normally pulled low by the pulldown resistor.
