Abstract
H-bridges are important driving components for consumer electronics and industry controls. They also play an important role in technologies related to DC motor control. Conventional H-bridge drivers require dead-time generation to avoid the shoot-through current resulting from both upper and lower power transistors being turned on concurrently. Unlike the conventional H-bridge driver, this paper proposes an H-bridge driver based on a complementary MOSFET type using gate bias, without a dead time generator, to improve its driving efficiency. Moreover, this proposed H-bridge driver also has a reduced hardware complexity.
