Electrical systems are now being used in applications that were formerly powered by hydraulic or pneumatic sources. These new systems are helping to makes future Aircraft more fuel-efficient, quieter, and environmentally friendly. However, this requires advancements in electrical, electronics, and control systems. One of the main challenges of the MEA is the reduction of weight and improvement of efficiency and reliability, which can be achieved by replacing the hydraulic actuator (used in modern aircraft to move the control surface to control the plane), with the electrical actuator, where control surface can simply be controlled by controlling the motor which is fed by the converter. This research aims to analyze the critical points of the converter to machine chain used in the actuation system of More Electric Aircraft (MEA).
