Gate Drive transformers are typically designed to operate from 10 KHZ to 100 KHZ. Designs above 100 KHZ are possible, but noise and inductance considerations usually prohibit higher frequencies. The function of the gate drive transformer is to generate an output voltage to turn on a gate drive that regulates high voltages in the KV range. Key design considerations include  isolation, leakage inductance and inductance. Isolation parameters should include high pot level, Insulation resistance and BIL rating. Leakage inductance reflects the stability of the output voltage versus the input voltage and helps to insure the output waveform edges are sharp enough prevent “false triggers”. Another consideration is whether or not the transformer inductance has the stability factor required to prevent over damping or under damping.
