Switching a SiC MOSFET Power Module creates two significant problems that need to be addressed in order to optimize the performance of the device: turn-off voltage overshoot and ringing. These two parasitic problems need to be controlled while maintaining efficient switching. Microchip’s AgileSwitch® line of patented Gate Drive products address these problems...

As vehicle electrification proliferates the consumer EV segment, other forms of transportation are also chasing the global macrotrend. Today, designers are finally able to extract disruptive system-level benefits of SiC technology to shrink the size, noise, and field failures of auxiliary power units (APUs) in transportation vehicles.

Microchip’s AgileSwitch family of Digital Programmable Gate Drivers feature Augmented Switching technology to enable efficient and reliable control and protection of Silicon Carbide (SiC) MOSFET devices.

The “Walk Around the Block” webinar series addresses design challenges and trending topics relative to power electronics applications. In this series, we’ll focus on EV fast charging and highlight a variety of topics from our vendors Wolfspeed (On-board chargers), u-blox (Wireless communications), Analog Devices (Optimize switching) and Microchip (Power factor correction)...

A detailed review of selected gate driver circuits and the design considerations for various applications with GaN, this webinar covers the characteristics of different GaN topologies and their driving requirements, examples and experimental results of gate driver circuits for applications from low power to high power, and more...

One of the key metrics when choosing a gate driver is peak current. During the process of examining various competitor datasheets, make sure peak current is compared in a like-for-like manner. The time to turn a MOSFET/IGBT on and off relates to the current that the gate driver can deliver, but it doesn’t tell the whole story...
