Designing Gate Drive Circuits

[chieeeeef]

Hi,

Can anyone help me how to design gate drive circuits (step by step)? Or does anyone know any article/s that gives a step by step approach on how to design gate drive circuits? I would really appreciate it if anyone could upload a link or could direct me to articles regarding designing gate drive circuits. Thanks in advance.

Regards,

Hi VVV,

Thanks for the article. I just read the article you gave me. I somehow understood the article. What we were looking for was the gate current required to charge the parasitic capacitances of the MOSFET, however, what's next? We already know the gate current and gate voltage required to fully turn-on and turn-off the MOSFET but how do I choose the proper components that will produce the said requirements? This is what I meant from my earlier post. If for example, I would like to design a totem-pole driver to drive the gate of the MOSFET, what steps or how do I choose the components needed in a totem-pole driver so that I could satisfy the gate current and gate voltage requirements?

Thanks in advance.
