摘要
电压驱动的电润湿棱镜往往需要连接体积较大的附加电源装置进行手动调节,不利于电控系统与棱镜器件的集成,且不符合电润湿液体棱镜装置实际应用中体积小、便携化的要求。针对上述问题,本文设计了一种基于STM32单片机的电控系统,通过单相移相调压技术将直流电源输出的较低电压经脉宽调制升高到所需的电压,根据需求调整4路输出电压,驱动双液体棱镜实现二维液面偏转,使单元器件使用方便快捷且易于控制。采用COMSOL软件对模型进行仿真分析,验证了器件模型的正确性。
The voltage-driven electrowetting prisms often need to be connected to a larger additional power supply device for manual adjustment,which is not conducive to the integration of the electronic control system and the prism device.Meanwhile,it fails to meet the requirement of the small size and portability of the electrowetting liquid prism device in the practical applications requirements.Aimed at the problems above,an electric control system based on STM32 single-chip microcomputer is designed.The low voltage of the DC power supply output is boosted to the required voltage by the boost chopper circuit,and the four output voltages are adjusted according to the demand.The two-liquid prism is driven to the two-dimensional liquid surface deflection,which makes the unit device convenient and quick to use,and easy to control.The model is simulated and analyzed by COMSOL software to verify the correctness.
