摘　　要：采用IRF3808场效应管作为功率输出器件,基于直流电机的H桥脉宽调制(PWM)控制原理,设计了一款专门针对低电压大功率直流电机的电机驱动器。该驱动器提供死区时间生成逻辑,仅需一路PWM输入信号便可实现电机的正、反转及调速控制。试验测试表明,该驱动器具有工作电压低,输出功率大的特点,且其四个桥臂通过死区生成电路可共享一个PWM输入信号,从而能够简化驱动软件的设计。A high-power and low-logic-voltage DC motor driver based on the H-bridge PWM control using IRF3808 as its power output devices is proposed.The driver with dead time generation logic can control the DC motor rotate in a positive or reverse way and regulate the revolving speed.The experiment shows that the driver has the characteristics of low working voltage and high power output.And the H-bridge can be controlled by one PWM signal because of the dead time generation circuit so that the design of the software can be simplified.
