What are resonant gate drive techniques for power MOSFETs?
Resonant gate drive techniques are investigated and a new resonant gate drive circuit is presented. The presented circuit adds minor complexity to conventional gate drivers but reduces the MOSFET gate drive loss very effectively.
How does an active gate driver ( AGD ) work?
Conventional Gate Driver (CGD) circuits typically design for reliability in these systems by including a resistor between the gate driver and gate of the IGBT. This slows the switching waveforms, reducing stress on the IGBT while sacrificing efficiency. This solution is suboptimal, however, and as such Active Gate Drivers (AGD) have been
