    Hello everybody, i am new here.
    I have a project that called laser pulsed driver in milisecond. I need to get 2V, 100A, 200 milisecond pulse @ working frequency 20 KHz.
    Summary
    How to obtain a microsecond pulse using capasitors [Pulsed laser drivers], 2V, 100 A , 200 microsecond, 20 Hz.

    How should i start my project ? Do you have any sugegstion ?

    I have some ideas like using buck converter with igbt ?

    Thank you..

    20 KHz =5uS, may be 200 nanosecond pulse?

    Q=100A*200uSec=20000u= --> C=Q/deltaV=20000u/1V=20000uF (Vcc=5V, Vmax=5V, Vmin=4V Rdis=(5V-2V)/100A=0.03Ohm. We need a very high quality condenser.
