Simplified example of a single-ended transformer coupled gate drive using a pulse transformer. The circuit might require additional components like diodes, depending on the drive circuit. ¹⁾

N1 - primary winding
N2 - secondary winding
R - gate to source load resistor
C - AC coupling capacitor
T - MOSFET
