Hello! Lastly i was designing a toy car moving in both direction foward and backward using relays and switches. I thank everybody who helped me. Now i want to move to h-bridge. i have read many books about the h-bridge but one problem that i still have is how to chose power FET transistors. Actually, i want to design a H-bridge for a 3V DC Motor. What type of Power FET am i going to use? Thanks in advance.
