资料介绍

利用光电耦合器、运算放大器、浪涌电流抑制电路和开关电源,设计了脉冲指令开关机控制电路。通过控制开关电源浪涌电流抑制开关管的开通和关断,实现设备电源的开通和关断。该开关机控制电路,不含力学敏感元件,初始状态锁定在关机状态,指令驱动电流小于2mA,可适应各种幅值的指令,指令电路和被控电路电气隔离,可靠性高。

The pulse command on-off control circuit was designed based on opto-couplers, operational amplifier, inrush current suppress circuit and switch power supply. The inrush current suppress circuit of switch power supply was turned on and off to realize device power up and down. The on-off control circuit comprised no mechano-sensitive devices. The initial state locked in off state. The command's driving current was less than 2 mA. It's compatible with different amplitude commands. The command circuit was electrically isolated from the controlled circuit, and it's highly reliable.
