In this chapter, firstly, converter types of switched reluctance motor (SRM) are described. Current control structure of SRM, which has six stator and four rotor poles, over an asymmetric bridge converter, is also explained. While feeding SRM by an AC grid, grid voltages have to be converted to DC voltage; to realize this conversion, in order to obtain high power factor and sinusoidal grid current, power factor correction (PFC) circuits must be used. In this study, an asymmetric bridge converter of SRM is fed by three-phase PFC boost converter that consists of uncontrolled diode rectifier and DC-DC boost converter with high frequency operation. PFC boost converter is controlled by nonlinear control algorithm. By means of the simulations that are conducted by MATLAB/Simulink, grid voltage and current, current harmonics of each phase, threephase currents of phases, flux, and current of SRM are presented. Simulation results show that proposed SRM that is fed by three-phase PFC boost converter system gives the desired performance, for both grid and SRM side.

The power density enhancement of a four‐phase switched reluctance motor using rotor conducting screens and DC‐link voltage boosting for electric vehicle applications is studied. The effect of conducting screen thickness and material electrical conductivity on current rise time, developed torque, and output power is studied. Different screen shapes are compared that elicit the optimum screen design by formulating a multi‐objective optimisation problem based on maximising the developed torque and efficiency and minimising added material weight. A double arm common switch converter with a DC‐link voltage‐boosting capacitors is deployed. The boosted voltage provided by the capacitors aids the winding current to rapidly build‐up; thus, increasing the motor base speed, whence power rating. Finite element analysis results confirm the SRM drive's effectiveness in increasing the motor base speed and improving the torque range; hence make the power capability of SRMs to be competitive with an equivalent volume permanent magnet synchronous motor.

This paper presents a review of the electrical and electronic technologies investigated in moreelectric aircraft (MEA). In order to change the current situation of low power efficiency, serious pollution, and high operating cost in conventional aircraft, the concept of MEA is proposed. By converting some hydraulic, mechanical, and pneumatic power sources into electrical ones, the overall power efficiency is greatly increased, and more flexible power regulation is achieved. The main components in an MEA power system are electrical machines and power electronics devices. The design and control methods for electrical machines and various topologies and control strategies for power electronic converters have been widely researched. Besides, several studies are carried out regarding energy management strategies that intend to optimize the operation of MEA power distribution systems. Furthermore, it is necessary to investigate the system stability and reliability issues in an MEA, since they are directly related to the safety of passengers. In terms of machine technologies, power electronics techniques, energy management strategies, and the system stability and reliability, a review is carried out for the contributions in the literature to MEA. INDEX TERMS More-electric aircraft, machine technologies, power electronics techniques, energy management strategies, system stability and reliability.
