- 摘要:
- 为了寻求一种简单、便捷的驱动控制电路,以实现电磁阀高电压开启、低电压维持的快响应工作模式,充分利用电气元件电容的充放电功能和电阻的分压功能,设计了“电磁阀线圈串接电阻和电容并联组”驱动电路。通过AMESim仿真软件建立电磁阀和驱动电路的仿真模型,对比分析了电容和电阻参数对线圈电流和响应的影响规律,并通过试验验证了该技术途径可以达到高电压开启、低电压维持的效果,实现了电磁阀的快响应目标。根据参数对比试验数据,启动电流峰值和上升率应通过选择电容参数来控制,维持电流应通过选择分压电阻参数来调整。该驱动电路技术可以推广应用于快响应电磁阀设计中,结构简易、操作简便。
- Abstract:
- In order to find a simple and convenient driving circuit and realize the solenoid valve with high voltage starting and low voltage sustaining rapid responsive mode,which full use of the electrical components function that the capacitance can charge and discharge and the resistance can share voltage,the driving circuit principle that the solenoid valve coil connected with resistance and capacitance which were parallel connected was designed.Through the AMESim simulation software, the simulation model of solenoid valve and driving circuit was establish,and the influence of the resistance and capacitance on the coil current and response was analyzed.Also it was evaluated by test that the solenoid valve can start rapidly at high voltage and maitain at low voltage,which meets the rapid response requirement.In response to the contrast testing data,a parameter of the capacitance to control current peak and rate-of-climb when opening can be selected,and a parameter of the resistance to control maintenance current can be also selected.The driving circuit technology can be extended and applied in the design of fast solenoid valve,with simple structure and easy to operate.
