How does an IGBT work? Meaning & Structure

When a positive gate voltage is applied, electrons accumulate under the gate and an n-channel is formed, just like in an NMOS. The p+ layer starts injecting holes into the n-drift layer and in exchange, starts extracting electrons from it. The electrons from the n-channel above start moving into the drift layer to help replenish the electrons lost.
