9.5 Gate loop layout

描述

2021年 3月 26日
In this lecture, we will learn:
  • Gate drive circuits have several loops that must be low inductance.
  • A “Kelvin connection” is often found on switching devices and allows gate drivers to bypass voltage drops in the high-current source path.
  • Gate resistors are often wanted for final damping, but are no substitute for good layout.
