An H-bridge driver using gate bias for DC motor control

DC motors are important rotation components for consumer electronics and industry controls, especially, DC motors also play an important role in the development of robot technologies. A design of DC motor driver, based on the H bridge using complementary MOSFET type, is proposed in this paper. Differing from the conventional DC motor driver requiring dead time generation, the proposed driver does not has a dead time generator by using gate bias. Therefore, this proposed H-bridge driver without dead time generation can not only reduce its hardware complexity, but also increase the driving efficiency.
