Gate driver design deep dive outline:
-Parasitics in gate driver-Gate driver soft/hard switching difference-Strong gate driver and MOSFET nonlinear COSS-Common mode transient immunity(CMTI), dV/dt and di/dt through parasitics L, and C?-How to separate power ground noise by PCB layout?-Power supply for isolated gate driver in UPS, server and Telecom system-TIDA and Experimental waveforms
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.
This training video summarizes the content of this gate driver series and the key references.
The presentation addresses the design consideration of USB Type-C power delivery. USB Type-C is the new trend of Industrial, automotive and personal electronics devices. In the training, audience will be able to learn more about USB Type-C power delivery (PD) requirement and understand architecture of USB Type-C PD, AC/DC power source.
