摘要
针对利用离子消除静电技术的具体要求,设计了一款高效的控制电路。该电路方案结合控制理论和X射线产生基础的技术要求与结构特点,通过比较分析,在控制电路中选取高效PWM控制芯片UC2845;加入PID闭环控制电路,优化MOSFET功率管驱动电路输出波形,提高了输出效率。而高压部分则采取负高压模式,解决了安全及散热等实际问题。整体电路设计结合技术实现要求,给出了较为适宜的电路拓扑结构与设计方案。最后以此思路研制了一台光离子静电消除器,且通过实验证明达到了良好的预期效果。
Thispaper discusses a new kind of clean static electricitytechnology design with the theory of automatic control and X-radiation and also presents design scheme of circuit optimization through comparing with structure characteristics and technical requirements. With the algorithm of PID control and optimization of MOSFET power driving circuit the control unit has the advantage of high efficiency. With the negative high voltage control technique the system has less heat radiation and good reliability. A device designed according to up describing has been tested with the good quality and reliability.
