This paper evaluates and compares commonly used methods for analysis of waveform distortions in power supply systems, including one new wavelet-based method. The evaluation is performed using a set of selected test waveforms (TWs) that have known waveform distortion characteristics, representing various types of deviations from an ideal sinusoidal waveform with a constant magnitude and frequency. The presented analysis uses both stationary and nonstationary TWs, featuring low and high frequency harmonics, interharmonics and subharmonics, as well as the frequency and magnitude variations of the fundamental and nonfundamental (including dc) components. The capabilities of the considered methods to correctly identify and accurately quantify specific waveform distortion features are evaluated by three general types of error metrics: a) statistical error indices, b) energy-based quantities, and c) waveform-related indicators. The combining of these metrics allows for a more detailed comparison of the original time-domain TWs with the waveforms reconstructed by the different methods. The presented results are part of the efforts to formulate a general methodology for a physically relevant evaluation of accuracy of different methods and specification of standardised test waveforms for a direct and comprehensive comparison and benchmarking of different methods.

Induction motor drives play an essential role in industrial production. Energy saving of induction motor drives is a very popular topic. Therefore, studies on the techniques to improve energy efficiency of a motor drive system are important. Major solutions to improve energy efficiency can be divided into two categories, i.e., via hardware, e.g., design highly efficient motors, and through software, e.g., advanced control methods. In this work we present a predictive control strategy to improve the energy efficiency of an induction motor drive system. In the proposed solution, the power factor can be directly manipulated by a properly designed cost-function. Compared with the classical control strategies (here refers to the field oriented control, predictive current control, and predictive torque control), the proposed one is able to effectively improve the efficiency of induction motor drives. Simulation results confirm the effectiveness of the proposed strategy.

The introduced prototype machine is a downsized demonstrator of an outer rotor wind generator combining a tooth-coil winding with a solid rotor yoke. The air gap field space harmonics of the tooth coil winding lead to significant eddy currents in the solid rotor yoke, which are investigated by analytical and numerical models as well as by measurements of the built prototype. While the analytical model is primarily useful to identify the dominating space harmonics, the 2D non-linear FE simulation leads to quantitative results matching the experimental data.

Electromechanical actuators (EMAs) begin to have a greater presence in current aeronautic designs due to the energy efficiency and reliability advantages they can provide. However, the conventional mechanical design with a single combination of a ball screw and an electric motor is subject to scenarios in which a single point of failure can render it inoperative. This paper presents a failsafe innovative EMA that gives a solution to the most typical jamming issues of aeronautical electromechanical actuators, either due to ball screw or electric motor failures. Different electric motor synchronization techniques applicable to the presented mechanical EMA design are analysed, and the benefits of the most adequate control strategy, the virtual line-shafting (VLS), are validated. Finally, the implementation of the control algorithm in a simplified virtual test bench with promising results is shown. The obtained results demonstrate that the proposed novel EMA mechanical design can enhance the failsafe capabilities of the current EMA designs based on a single ball screw and motor combination.

The hybrid-electric propulsion control system plays a fundamental role to ensure the correct function of all components and to operate a performing energy management. Several control strategies have been proposed in the literature, but the challenge is to keep these techniques methodologically simple and easy to implement. In this paper, an analytical derivation of the Equivalent Consumption Minimization Strategy (ECMS) for energy management of hybrid-electric aircraft is presented, based on Pontryagin’s Minimum Principle (PMP). Simulation results obtained for a parallel hybrid electric configuration with a maximum take-off power of 134 kW are also presented.

In this paper, a new structure of bidirectional low dc/dc converter (BLDC) with low profile, i.e., 25mm and without no fan is proposed for direct connection between a battery pack and BLDC converter. For its implementation, the DAB and interleaving converters with 2-stage are adopted.In order to achieve BLDC with low height and high efficiency, the transformer and secondary rectifier in DAB converter are respectively separated into two planar-type transformers with series-connection and two rectifiers with parallel-connection. Moreover, in two interleaving converters, their input/output is connected in parallel and interleaved control is applied. In addition, doubled heat sink structure of paralleled FETs on high current is applied.To verify its performance such as its static/dynamic operations, efficiency, and temperature, a 500W prototype with 650V input and 1V$sim$5V output was built.

This paper presents a loss model for SiC MOSFET based power modules without external freewheeling diode. In current electric high perfomance drives for electric vehicles, a low material input, reduced costs, reduced construction volume with maximum efficiency and thus an increased power density play a crucial role. At the same time, the wide bandgap materials should be fully utilised with maximum switching gradients under the given boundary conditions of the power module, the commutation cell design and overall systemic aspects. Absolute maximum ratings and failure in time rates play a important design role in ensuring reliable power modules for the service life of electric vehicles. It is not only the technological leaps in assembly and connection technology that make a decisive contribution here, but also a wide variety of control methods, alternative converter topologies and of course novel semiconductor materials that have an influence on efficiency, thermal properties, volume and thus the use of materials. The maximum efficiency in the present application can be increased by a suitable gate control that leads to synchronous rectification. Due to the multitude of control concepts and the use of a fully variable switching frequency and the influence on the harmonic spectrum, harmonic losses are also analysed and evaluated using a high-speed numerical model. In addition, an analytical loss model is derived and subsequently validated and discussed on the test bench.

Mild-hybrid market requires smart and flexible power conversion systems that dynamically adapt their behaviour according to the working conditions and operational needs. This sector also asks for high-efficient converters with limited dimension and weight. Optimal versatility and high power density can be achieved thanks to monolithic GaN technology. In this context, this paper presents a 48-12V interleaved conversion system based on the emerging GaN technology combined with a closed-loop control implemented using the STM32 microcontroller. The main feature of the proposed system is the dynamic closed-loop control implemented by the microcontroller that modulates the driving signals for the interleaved power stages at different load conditions. The microcontroller also introduces the important feature of overcurrent protection to increase the security level of the whole system and react in case of failure. The proposed system combines the improved switching behavior of the GaN compared to silicon and the interleaved synchronous structure to obtain 95% peak efficiency.

In this paper, a data-driven continuous control set model predictive current control (CCS-MPCC) scheme for permanent magnet synchronous motors (PMSMs) is proposed. The model of the motor used in the model predictive control (MPC) strategy is obtained from collected measurements using the Koopman operator (KO) theory. Experimental results on a 500W PMSM show that the obtained model has yielded excellent prediction accuracy, and that it is capable of being incorporated within a real-time CCS-MPCC scheme in the sub-millisecond typically available sampling time for the current control loop of synchronous motors.

This paper presents the design considerations for a 48V multiphase GaN inverter to drive a six-phase permanent magnet synchronous motor (PMSM) with 25kW/35kW of continuous/peak power. This electric drivetrain system can be foreseen as an emerging technology for urban-sized electric utility vehicles. The inverter’s critical components such as GaN switches and dc-link capacitors are pre-sized using analytical calculations whereas a liquid-cooled heatsink is designed using finite element analysis with Ansys Icepak. The prototype of a half-bridge phase module is manufactured to evaluate the gate driver board’s capability for the high parallelization of GaN switches and the PCB layout of the power board based on an insulated metal substrate. Preliminary experimental results are presented to demonstrate the feasibility of the study.
