Study on design and electro magnetic compatibility of high-power pulse driver

A kind of high-power pulse driver is designed to drive semiconductor laser. The circuit consists of three parts: generator of pulse signal, power amplifier of pulse signal and storage circuit controlled by metal-Oxide-semiconductor field-effect transistor (MOSFET). According to the experimental results, this kind of high-power pulse driver well restrained the pulse spike and overshoot by proper design, better choice of components and improvement of electro magnetic compatibility (EMC). The circuit can output pulse signal with better quality, which provides qualified driving signal to laser diode. The pulse width is under 50 ns and the output ranges from 10 A to 50 A.
