摘要
固体继电器需要使用光隔离电路,其中主要使用了既能起到隔离作用又能为开关器件提供驱动电压的光电池器件。固体继电器要求光电池的输入电流尽可能小,传统光电池在较小输入电流下输出电压能力不足,输出电压一般不大于5 V,造成其他开关器件不能正常工作。为了改善光电池器件输出电压的能力,优化了结构设计,在光电池器件内部填充了光学胶,使光电池的输出电压超过了6 V,满足开关器件的使用要求。
The optical isolation circuits are often used in solid-state relays,in which the main use is a photocell device that can both play the role of isolation and provide driving voltage for switching devices.The solid-state relays require the input current of the photocell as small as possible.Traditional photocells have insufficient output voltage capability at small input currents,and their output voltages are generally not greater than 5 V,resulting in other switching devices not working properly.In order to improve the output voltage capability of the photocell devices,the structure designs are optimized.The photocell devices are filled with optical adhesive,and the output voltages of the photocells exceed 6 V,meeting the requirements of switching devices.
