Must Knows of Gate Driver for ZVS Converter

In this training video, soft switching ZVS converters, including totem-pole PFC and LLC resonant converter, is mentioned to improve all the all the issues of hard-switching, especially the reverse recovery of the diode. Differences of gate driver on hard-switching and soft-switching is highlighted and explained. New issues of soft switching, high turn-off current, is also discussed with strong gate driver to minimize the turn-off loss. LLC resonant converter turn-off loss mechanism is illustrated in depth.
