Wideband gap devices (SiC and GaN) are key drivers to improve power supply efficiency and compactness, but limited performance is achieved due to more design difficulties in fine tuning and controlling the power supply using standard analog drivers. Digital control is the key solution to satisfy all these needs. With increasingly powerful microcontrollers available on the market, it is now possible to digitalize the power supply. In the presentation we will show how the combination of Wise Integration's WiseGan® power IC and WiseWare® digital control, simplifies the power supply architecture by reducing and eliminating external components and heat sinks. It will be demonstrated that extending WiseGan® power electronic devices with WiseWare® digital control is an optimal and compelling way to achieve the most efficient power supplies while improving system size, weight, cost and reliability.
Thierry Bouchet is doctor in Electrical Engineering in 2001 and worked for IBS (Ion Beam Services) and Atmel, two semiconductor companies. In 2011, Thierry created a fabless start-up (ADIS) in the area of power electronics for niche market. He joined CEA Leti in 2014 and worked on developing of GaN components before becoming Strategic Marketing manager for energy and power electronics. He is today the CEO of Wise Integration, a startup which he launched in 2020, for the ultimate power supply miniaturization solution using GaN Integrated circuits and digital control.
