H Bridge Motor Driver Using Mosfet. Q1 and q4 provide a current path for the motor but in the opposite direction for the current flow. To get the answer of all these questions reading the following article.
However in practice we can expect to get currents up to 40 a if the mosfet temperature is kept as low as possible using a big heatsink or even a fan. High efficiency rotation direction change and braking the motor. Q1 and q4 provide a current path for the motor but in the opposite direction for the current flow.
H bridge configuration requires both p and n type mosfets but since n type mosfets have improved electrical characteristics using only n type for four of the transistors will be ideal.
Here we turned off opto coupler oc1 turns q1 on and q2 off and turned on oc2. It is the simple and elegant solution to all motor driving problems. The h bridge motor driver circuit. The mosfets are used as switches and are activated in diagonal pairs.
