Gate Drive Transformer Waveforms

What gate drive transformer core duration.

Gate drive transformer waveforms.

This circuit is limited to 50 duty ratio. For wide duty cycle applications such as buck converters it doesn t provide adequate gate drive voltage and thus a dc restoration circuit has to be added on the secondary side of the transformer capacitor and diode coupling capacitor voltage increases with duty ratio increase and also.
