This paper proposes a capacitor voltage regulation method for the dual converter with a floating bridge for aerospace applications. This topology has previously been reported, but with a constrained voltage utilisation factor due to the need for capacitor voltage regulations. In this paper, the effect of switching states on the voltage variation of capacitor is quantitatively modelled and an enhanced space vector modulation scheme with current feedback is proposed to achieve an active control of the floating capacitor voltages. This proposed method also allows further exploitation and utilisation of converter voltage. The relationship between the allowed modulation index of dual converter and load power factor is obtained and expressed using a fitted polynomial equation. The advantages of the proposed method include boosted voltage utilisation and superior performance in term of capacitor voltage balance. These advantages have been proven through simulation and experimental results on RL loads as well as with an open-end winding induction motor. The proposed modulation scheme can boost the converter voltage utilisation by at least 10% while achieving full four-level operation. More importantly, the higher available voltage allows extending the constant torque region of the motor, the further beginning of field weakening operation could be postponed.

“…From a more system-level perspective, an innovative solution to replace the clutch system is presented in [97]- [100]. A conical two degrees of freedom induction machine, whose shape and geometry permit both rotational and axial movements, would eliminate the need for the mechanical clutch and the ensuing challenges associated to it, such as the need for accurate synchronization between wheel and TM.…”

The ever-increasing demand for passenger air traffic results in larger airline fleets every year. The aircraft market forecast reveals an unprecedented growth for the coming decades, leading to serious environmental and economic concerns among airlines and regulatory bodies. Different approaches, for both airborne and ground operations, have been proposed to reduce and control emissions without compromising profit margin. For on-ground activities, the electric taxiing (ET) methodology is one of the suggested solutions for reducing the emissions and the acoustic noise in the airport, and for lowering the fuel consumption and operating costs. This paper thus aims to review and collate the more important literature related to electric taxiing systems (ETSs), in order to draw an inclusive picture regarding the current state of the art of a moving and growing sector that just started its first steps towards an ambitious target. After introducing the general concept of ET, elaborations on the benefits and challenges of available technologies are done with a detailed comparison of the different systems. Finally, recommendations for future research and outlook on ET are presented.

This study investigates the thermal impact of using different winding topologies and different winding encapsulation materials on dual‐stator 6/4 flux‐switching permanent magnet (FSPM) machine with water jacket cooling. The thermal performance of four different design cases are compared using lumped‐parameter thermal network models. The modelling of the heat transfer in the stator slot, machine air gap and water jacket channel are presented. It is shown that FSPM machines with circumferential winding and toroidal winding have different thermal limiting components and the winding encapsulation material has a different impact on the thermal performance of the two winding topologies. Prototype motors are built and tested to validate the thermal models.
