In this training video, parasitics in the gate driver system is identified. Piece-wise linear switching sequence at turn on/off is illustrated. Reverse recovery introduced additional complexity on turn-on transition is explained with comparison of MOSFETs and IGBTs.
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.
This training video discusses the strong gate driver introduced high dv/dt and di/dt during turn-on and turn-off switching transition, and also illustrate the high dv/dt and di/dt introduced noise through the parasitic capacitance/inductance on high side level-shift and junction capacitance on the bootstrap diode. Solutions with new state-of-the-art gate driver and its key features are introduced and explained.
