摘　　要：搭建以TMS320F28335为核心的脉宽调制(PWM)数字化输出与信号处理系统,结合位置式PID控制算法,调整PWM信号占空比,控制半桥驱动电路的功率,提供多种工作模式,实现不同工作功率输出.相较于传统的模拟控制技术,该编程解决了半桥死区时间控制.设计隔离式碳化硅高频半桥驱动电路,解决了SiC MOSFET驱动串扰抑制,优化开关速度,减少功率电路对小信号处理的干扰.实验结果表明,该数字化信号驱动系统具有稳定、灵活、可靠控制高压气体放电灯(HID)输出工作功率,为公共照明电路的控制带来便利与高效.PWM digital output and signal processing system with the core was constructed,and combined with positional PID control algorithm,the PWM signal duty cycle was adjusted to control the power of the half-bridge drive circuit;multiple operating modes were available to achieve different operating power outputs.Compared to traditional analog control technology,the problem of half bridge dead time control was solved by programming.An isolated silicon carbide high-frequency half-bridge driver circuit was designed.It can solve SiC MOSFET driver crosstalk suppression,optimize switching speed,and reduce interference of power circuits with small signal processing.The experiment results showed that the digital signal driving system can control the HID output operating power in a stable,flexible,and reliable manner,which brings convenience and efficiency to the control of public lighting circuits.
