More electric aircraft referred to as the general move in the aerospace industry to increase the amount of electrically powered equipment on future aircraft. One of the most important kind of electric loads of the future more electric aircraft is the aircraft electric actuator but its power characteristics possesses rapidly varying nature in the wider range and constant power nature in the smal...

Electric locomotive is a kind of high power rectifier load, and its load characteristics will have a significant impact to safe, stable and economic operation of power system. This paper mainly analyses load characteristics of harmonic and reactive power for electric locomotive. Simulation model of electric locomotive is set up based on time trigger; it is so better conform to the dynamic chara...

Active heat flow control is essential for broad applications of heating, cooling, and energy conversion. Like electronic devices developed for the control of electric power, it is very desirable to develop advanced all-thermal solid-state devices that actively control heat flow without consuming other forms of energy. Here we demonstrate temperature-gated thermal rectification using vanadium di...

The main contribution of this paper is the use of sensorless active diodes to generate the gate signals for a three-phase boost-rectifier with a self-powered control scheme. The sensorless operation is achieved making use of the gate control signals generated by the active diode schemes on each of the switching devices using a pulse width half-controlled boost rectifier modulation technique (PW...

The three-phase induction motor is the main electric used in industrial applications, contributing significantly to electricity consumption. Additionally, traditional variable speed drivers, due internal constitution based on a passive rectifier, co
