Controlling gate-source voltage with a gate driver in a secondary-side integrated circuit (IC) controller for a secondary-controlled AC-DC converter is described. In an example embodiment, the gate driver is configured to programmably control the gate-source voltage and the slew rate of a ...
This paper presents a gate driver, which has output voltage with double source voltage. Such a gate driver can reduce the number of voltage sources required to power a complicated system, such as a servo system. And hence, the space for the overall system can be decreased. The detailed oper...
Furthermore, because the experimental GaN transistors are normally-on, the drivers need to be robust so that they apply a negative gate-to-source voltage to switch off the transistor in case an error occurs in the driver. A third requirement for the drivers is that it has to be easy to ...

The totem-pole output stage, capable of 600 mA source and 800 mA sink current, is suitable for big MOSFET or IGBT drive. This, combined with the other features and the possibility to operate with ST's proprietary fixed-off-time control, makes the device an excellent solution for SMPS up ...

In addition, a behavioral study of the effective channel mobility with temperature variation in the SiC MOSFET will be investigated.• Designing a gate driver which fits with the driving requirements of the SiC-MOSFET and provides a trade-off between the switching losses and the EMI behavior....
In a level shifted high voltage MOSgate device driver which drives MOSgate devices such as IGBTs and power MOSFETs, effects of negative voltage swings caused by currents commutating through L.sub.S1 and L.sub. S2 inductances in the power circuits are avoided due to several measures. First,...
