An integration of an electric motor and a drive with wide bandgap (WBG) devices possesses numerous attractive features for electrified and decentralized actuation systems. The WBG devices can operate at high junction temperature (>170°C) with improved efficiency due to fast switching speed and low on-state resistance. It also leads to better performance and higher power density electrohydrostatic actuators than the traditional solutions, which are being widely adopted in industrial applications such as aerospace, robotics, automobiles, manufacturing, wind turbine, and off-road vehicles. This paper introduces and investigates the benefits of the integrated motor drive (IMD) with the WBG-based power electronics for the electrohydrostatic actuation systems.
