摘　　要：无创呼吸机核心技术之一是控制电路控制涡轮风机运行,产生满足呼吸病患者呼吸生理需求的通气气流。为实现安全可控的气流输出系统,基于无刷直流电机控制专用芯片MC33035和速度测控专用芯片MC33039,设计了三相无刷涡轮风机的控制电路,实现了输入模拟电压来线性控制涡轮输出气流。该电路将作为模块嵌入到无创呼吸机系统,在硬件电路上为其输出稳定、可控的气流提供保障。One of critical technologies in a non-invasive positive airway pressure respirator is to output the airflow for meeting the requirement of respiratory patient in breath.In order to develop a safe and reliable blower driving system,a circuit based on the special chips MC33035 and MC33039 was designed.The linear relationship between the input control voltage and the output air flow was achieved.This designed circuit will be embedded in the non-invasive ventilator system as a module.And based on this circuit,the secure and controllable ventilation flow can be performed.
