The electrification of vehicles is seen as a central option to tackle the societal challenges of climate change and energy conservation. To minimise the impact on our environment and natural resources, car manufacturers are opting for a smart, green and integrated transport system that requires highly efficient and compact drivetrain solutions. This is a complex task for motor designers in view of the multiple objectives and constraints that involve both mechanical, thermal and electromagnetics effects. Powerful multidisciplinary design procedures are therefore necessary to get accurate and comprehensive results in a computationally efficient way. This paper aims to present the optimisation of a high speed copper rotor induction motor for a traction application using Motor-CAD and optiSLang software. The main goal of the research is to design a rare-earth free magnet motor for the next generation electric powertrains, while ensuring the industrial feasibility for mass production at low manufacturing costs and providing higher performance than current technologies. The selected approach combines cutting edge sensitivity analysis, metamodeling and optimisation techniques in order to provide an optimum design with respect to given specification. The motor is optimised first electromagnetically, then thermally, while the mechanical behaviour from a rotor stress point of view is evaluated at the end of the process.

In this paper, a method for lifetime estimation of insulated-gate bipolar transistor (IGBT) power electronics (PE) modules in offshore wind turbine (WT) applications is presented. The PE module is studied using a time-series WT simulation model. The WT model employs a detailed representation of the system, including a two-mass representation of the mechanical side, d-q representation of the permanent magnet synchronous generator (PMSG), and an appropriately controlled back-to-back voltage-source converter (BVSC). Additionally, in order to monitor the temperature cycling, a thermal model which considers the losses in an IGBT module has been added. The temperature cycles are counted using a rain flow algorithm and the resulting effect on lifetime is calculated using Miner's rule for damage accumulation. The system is parametrised according to current state-of-the-art offshore wind turbine technology.

This work proposes a straight forward approach for the utilization of Direct Torque Control (DTC) algorithm to drive an openend winding Synchronous Reluctance Machine (SynRM). The drive is based on an Indirect Matrix Converter (IMC) with Dual Voltage Source Inverters (DVSI) on the output, thus eliminating the need for a dc-link. The proposed approach only utilizes the the output vectors that eliminate the contribution of the dual inverter to the Common Mode Voltage (CMV), improving the drive lifespan by reducing the machine bearing currents. The proposed Direct Torque Controller is based on four hysteretic controllers to allow the control of Torque, Flux, Zero Sequence Current on the machine while allowing input power factor correction by controlling the grid current.

This paper presents an advanced disturbance observer-based active flux estimation algorithm for sensorless control of IPMSM. The stability of the proposed active flux observation is guaranteed using the Lyapunov stability theory. The method does not require frame transformation, enhancing system performance by reducing computational time and system independence on the d-axis inductance. An improved PLL method is developed by analysing the approximation effect in the conventional PLL during a transient condition. A MATLAB simulation is applied to validate the approach.

Resonant Switched Capacitor (SC) DC-DC converters are showing potential for use in medium to high-power applications. The high-cell count in these applications means that for a given voltage conversion ratio there are theoretically a large number of alternative topologies that can be synthesised. However, each of these topologies may exhibit different competing characteristics, for example total VA rating of capacitors, total VA rating of switches, number of switches and individual switch voltage rating. Obtaining an optimum topology in terms of given design constraints is therefore important requirement. This paper builds on previous work by the authors by presenting a method for the automatic calculation of the voltage ratings of the components in a SC converter. This result along with earlier work, allows for the calculation of VA ratings, which are an important metric when comparing competing circuits. In addition, a new Canonical Cell topology is presented that extends the range of SC circuits that can be analysed using this method, to cover so-called Ladder circuits. The method is validated against detailed Spice simulations and measurements from a hardware prototype.

Current environmental concerns have led to the partial electrification of the air transport, following the well-known more electric aircraft (MEA) concept. In such aircraft, electromechanical actuators (EMA) are being progressively introduced to substitute hydraulic actuators. In EMA systems, multiphase technologies are gaining popularity due to their high power density and fault tolerance; however, complexity is increased. To accelerate the early development stages of such systems, real-time simulation can be considered. This work presents a real-time simulation platform for a landing gear EMA implemented in an RT-Lab digital simulator, where the multiphase power system is simulated in an FPGA.
