Half bridge coupled resonant gate drivers
In accordance with an embodiment, a method of controlling a switch driver includes energizing a first inductor in a first direction with a first energy; transferring the first energy from the first inductor to a second inductor, wherein the second inductor is coupled between a second switch-driving terminal of the switch driver and a second internal node, and the second inductor is magnetically coupled to the first inductor; asserting a first turn-on signal at the second switch-driving terminal using the transferred first energy; energizing the first inductor in a second direction opposite the first direction with a second energy after asserting the first turn-on signal at the second switch-driving terminal; transferring the second energy from the first inductor to the second inductor; and asserting a first turn-off signal at the second switch-driving terminal using the transferred second energy.
