New Power MOSFET Technology for High Efficient Motor Drives

Abstract:
This work introduces the characteristics and properties of the latest trench MOSFET technology for high power density motor drive applications. A revolutionary new cell design is combined with the benefits of an advanced manufacturing technology, bringing benefits of low conduction and switching losses with good ruggedness, excellent body diode properties and an extremely tight threshold voltage spread. These features result in a well-balanced all-round performer that will bring significant improvements to e-scooters, microEVs, forklifts, golf carts, light electric aircraft, and other battery-powered motor drive applications, which require an easy paralleling of many devices. The presented results focus on the use of the new devices in such applications.
