The number of decentralized generation units (e.g., wind and solar energy) and loads (e.g., heat pumps and EV-chargers) in the electrical distribution grid are increasing. Most of these sources and loads are coupled by power electronic converters to the main grid. In the low voltage distribution grid level, single-phase or three-phase devices with a neutral connection can lead to harmonics at zero sequence component. Compensation of the zero sequence component requires a grid regulator with a neutral line connection and a suitable control methodology. Consequently, a power electronic inverter with split dc-link capacitors with a neutral connection is considered in this paper. The device is modelled in the symmetrical component (SC) domain and differentiated to each individual harmonic order. The transformation from the time to frequency domain is based on the heterodyne dq-transformation and the SC domain. This results in a decoupling of the control parts in terms of harmonic frequency and the sequence components (positive, negative, zero sequence). Moreover, the coupling of dq-components of the system is compensated by individual resistance to reactance ratios (R/X) decoupling terms. The validation in simulation and a real hardware test shows the strength of the control approach.

This article is dealing with the issue related to the matrix converters (MxC), especially with the analysis of the power losses and efficiency of the matrix converter in a $3times 5$ configuration. In today’s modern world, efficiency is especially taken into the account, so analysis of the power losses and efficiency is a great deal during the design process of the modern semiconductor converters. The faster evaluation of the power losses can significantly reduce the required design time. The presented model is using modern SiC semiconductors which have significant advantages in comparison to the IGBT transistors. The model of the $3times 5$ converter is presented together with power losses analysis in different parts of the converter eg. the power circuit, input filter, and so on. At the end of the paper summary of the simulated results is presented together with the pros and cons of using SiC semiconductors in bidirectional switches for matrix converters.

Double pulse test is the industry standard for determining the switching characteristics of a semiconductor switch. The component manufacturers implement the double pulse test with a dedicated test setup with favorable layout for minimizing the switching loop inductance. Such layout and minimized loop inductances may not be implemented with different inverter topologies. Therefore, independent tests must be done for each switch of the phase-leg to ensure the switching behavior for each possible commutation loop. This procedure becomes more critical with more complex phase-leg structures of multilevel inverters. This paper presents a double pulse testing method dedicated for a phase-leg of a three-level neutral point clamped inverter. With the proposed method, all of the commutation loops within the phase-leg can be tested at nominal voltage rating with half of the nominal DC link voltage as input. The method is verified with experimental results using a phase-leg of a medium voltage three-level neutral point clamped inverter using 4.5 kV rated insulated-gate bipolar transistors.

Research on multiphase machines is a hot topic in the field of power electronics and drives. Due to the greater number of phases, they provide better properties. Research in this area is moving forward rapidly. There are already many studies that compare the properties of conventional three-phase induction machines with multiphase machines. One of the most frequently compared features is the fault tolerance of the engine. We know that multiphase motors provide more degrees of freedom that can be used to make the motor more fault tolerant. A safety operation of the motor is one of the most important topics in the field today. This is due to the massive introduction of electric vehicles. This work deals with the fault tolerant for a five-phase induction machine. The article presents interesting results with the possibility of controlling of five-phase induction motor, which ensures the improvement of the properties during the failure.

To the stability study of electrical power network, the Middlebrook criterion is the mostly accepted method, which examines small signal stability of averaged models. Only the input impedance of the load subsystem and the output impedance of the source subsystem and their Bode diagrams are needed. The analytic calculation of the input/output impedances may be extensive while there is no information on the sensitivity of the impedances to parameter variations available for a hardware measurement approach. In this paper an approach for stability of power systems for More Electric Aircraft using the Middlebrook criterion and the eigenvalue method is applied to assess the small-signal stability. Stability analysis of this class of systems is crucial due to the potential for negative impedance instability.

Due to their high efficiency, LLC-type converters have gained wide application fields, e.g., as DC-DC converter stage in automotive chargers or in power supplies in industrial applications. The amazingly high efficiencies of 97 to 98%, in some cases up to 99% are achieved by zero-voltage switching techniques that allows the use of Superjunction MOSFETs with small channel resistances but relatively large parasitic capacitances. However, if the converter is to be operated in wider voltage gain range, operation at the lower end of this range can result in a huge switching frequency which would degrade the good efficiency. The idea presented in this paper is to make use of inductors with a resonance of the magnetic field. As a result, the switching frequency would have to be varied only in a smaller range. The idea is particularly aimed at future designs with switching frequencies approaching the MHz range as it will occur with GaN transistors very soon. In this frequency range, the wavelength within the magnetic material is only in the dimension of some millimeters so that the core geometry could be designed for certain resonance effects that would reduce the peak switching frequency considerably. However, this favourable effect could be impaired by other side effects such as increased losses, so the situation should be clarified by detailed experiments in the near future.

Generally, the operation of conventional DC-DC Cuk converter set on continuous conduction mode creates a high input current ripple and injects undesirable harmonics to the source. As a result, the interleaved DC-DC Cuk converter is utilized to mitigate the input current ripple. Since, high efficiency is important, in this paper, fully soft switched interleaved DC-DC converter is proposed which is done by a single auxiliary switch in its structure. The simple control circuit remains PWM. The converter is analyzed and simulated. The results approve the theoretical analysis at steady state condition.

This paper addresses reduction of 6f (6 times of electrical frequency, f-radial force harmonics with zero-order mode in an interior permanent magnet synchronous motor by injection of the zero-sequence third-harmonic current, which has only little influence on the motor performance. The injection frequency for reduction of 6f-radial force harmonics in the proposed method is half of that for conventional dq-harmonic current injection. Thus, the control of current injection can be easier. Furthermore, the proposed system with a three-phase four-wire inverter enables providing the zero-sequence current without additional power electronics circuit. To demonstrate the effectiveness of the proposed method, three-dimensional FEM analysis was performed using an IPM motor with 8-pole/48slots distributed winding. The analysis results indicated that the 6f radial force harmonics and sound pressure were reduced by injection of the zero-sequence third-harmonic current while the torque ripple is largely not changed.

Single stage dc-ac high-frequency link matrix converters (HFLC) are suitable for numerous applications where dc-ac conversion is required along with voltage matching and/or galvanic isolation. However, when bidirectional and reactive power processing is required, HFLCs lack effective modulation methods that would allow for operation without additional circuits or reduced performance. This paper presents a phase-shift modulation (PSM) method suited for bidirectional operation of HFLC. The proposed modulation can be used for both rectifier and inverter operating modes, with control over the power factor. Zero voltage switching (ZVS) of the dc-side switches and zero current switching (ZCS) of the ac-side switches is achieved in all operating conditions. Furthermore, two switches operate at line frequency, eliminating their switching loss. There is no need for auxiliary circuits and the same commutation principles are used in both power conversion directions. The modulation was verified on a PSIM simulation model

An energy efficient and transients optimal control for Interior Permanent Magnet Synchronous Motors is introduced based on the concept of the combined Maximum Torque per Ampere (MTPA) and total electric Loss Minimisation (LM) control approaches. The nonlinear optimal implicit equation of the combined MTPA/LM method is derived in a new compact form, the same as for the conventional LM approach. Then it is very simply applied to activate the MTPA control during transients for fast dynamics and the LM control during steady states for maximum efficiency. Compared to the existing similar approaches, it allows smooth transition between the methods with smaller number of equations simplifying required control coding and reducing the control algorithm execution time. Analytical results are supported by simulations and experimental results.
