Wolfspeed 1200V SiC MOSFETs Enable Bidirectional Charging for 200V to 800V EV Batteries

SiC MOSFET benefits apply to EV charging systems, and Wolfspeed’s 1,200V SiC MOSFETs not only offer performance enhancements but also allow for bidirectional charging/discharging, thereby replacing IBGT topologies and allowing for simple two-level implementations…


Technical Article: Energy Storage Systems Boost Electric Vehicles’ Fast Charger Infrastructure

Electric vehicles (EVs) will gain more and more market share, eventually taking over internal combustion engine vehicles. Direct current (dc) fast charging stations will replace, or integrate, petrol stations. Renewable energies will be used to power them, such as solar and wind. People will desire to charge their EVs in less than 15 minutes and they won’t want to wait in a queue for a unique charging pile...


Application Note: Characterization of a 62mm SiC Power Module with AgileSwitch Augmented Switching Gate Drivers

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...


Application Note: Reducing Size, Noise, and Field Failures of Transportation APUs

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.
