半导体激光器电源防浪涌电路的设计

Design for the Circuit to Eliminate Surge of the Laser Diode Power Supply

本文利用氧化锌压敏电阻、瞬态电压抑制器(TVS)以及慢启动电路设计了一款应用于半导体激光器的防浪涌保护电路,通过实际测量开关插拔瞬间电路的浪涌波形以及防浪涌保护的实际效果,测试结果证明该电路能够对该浪涌起到良好的防范作用,实现了对半导体激光器的防浪涌保护。

This text aims to design a kind of circuit which is used to protect the laser diode from surge by varistor, TVS and slow starting circuit. Through measuring the surge wave appearing at the time of switching on and off and measuring the real effect of the surge protecting, the result of the test has proved that such circuit does eliminate surge of the laser diode power and protect the laser diode.
