UCC21520 – Turn-Off with Negative Voltage

This training video will help to understand the UCC2152x's output configuration and grounding consideration when driving FETs and IGBTs with negative voltage bias. Three different implementation methods are introduced, pros and cons of each methods are illustrated.

Gate Driver Design Deep Dive

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

Parasics and its Influences at Hard-Switching

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.

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.

Gate Driver Operation with High dV/dt and di/dt

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.

Power Switching Device Cannot Drive Themselves - Mastering the Art of High Voltage Gate Driver Design in UPS, Telecom, and Servers

We live in a world where designers are constantly pursuing higher efficiencies and higher power densities. Our customers want more power out with less power loss, while achieving smaller solution sizes! They strive to reduce switching losses while maintaining signal integrity. The need for higher efficiency and power density is a trend seen across isolated and non-isolated power systems in Uninterruptible Power Supplies (UPS), Telecom Rectifiers, and Server PSUs.
