This paper presents an investigation on a non-isolated, three-level DC/DC converter; more specifically, on the possible combinations of inductor configurations and modulation techniques directly affecting the performance of the converter. The many state-of-the-art and conventional solutions are compared theoretically, as well as based on experimental considerations founded on a medium voltage SiC-based DC/DC converter to be applied as an energy storage interfacing system in a fast charging station. The study focuses on the effects of the configurations on the output ripples of the converter, which is crucial for battery-oriented systems. The tests were performed at 1 kV and up to nearly 10 kW of power, successfully validating the use of each configuration. It is shown that for a system to operate in a wide output range, the current ripple criterion is not enough for choosing the optimal configuration, and other factors, e.g., efficiency, must be considered.

The paper deals with the power supply systems for MicroGrid based on multilevel inverters. An analysis of promising voltage inverter topologies for use in MicroGrid power systems with renewable energy sources has been conducted. The development of power supply systems with PV cells using multilevel inverters is promising. An analysis of the operation of single-level inverters with impedance and quasi-impedance links in the input circuit showed that these devices are capable of meeting the specific requirements for inverters used in systems with RES. Multilevel topology enables work at higher frequencies and a larger factor of input voltage use. The use of an impedance (Z-inverter) or quasi-impedance link (qZ-inverter) additionally satisfies the need to ensure the continuity of the inverter’s input voltage. Multilevel voltage inverters with the ability to increase the amplitude of the inverter’s input voltage are a promising direction for the development of inverters for use in systems using solar panels as renewable power sources.

The biggest drawback of Neutral Point Clamped (NPC) converters lies in their inability to maintain voltage balance in the dc-link capacitors for some operating conditions when the number of voltage levels (N) exceeds beyond three. To overcome this limitation, NPC inverters are usually combined with active dc-link voltage generation by utilizing multi-winding transformers and controlled rectifiers, or by using a second NPC converter as an active frontend, thus resulting in a complex system. Moreover, previously proposed Multilevel Rectifier (MLR) solutions have relied on additional auxiliary circuitry for handling the dc-link voltage balancing. In this article, a Five-level NPC-based rectifier with a Time Division Multiplexing-based voltage balancing control is revealed and verified by digital simulations and controller plus hardware in loop real-time simulations. The proposed PWM-based control scheme allows the NPC to be operated as either a standalone MLR with an unbalanced resistive load or as an active frontend to drive a second NPC-based inverter, in which dc-link voltage balancing is carried out only from the rectifier side, while also maintaining the ability to control the power factor and the amount of reactive power exchanged with the ac grid.

Multiport converters are used in various applications, where it is needed to interface multiple sources and multiple loads. As an example, multiport converters are used in renewable energy applications, distribution grids, electric vehicles, etc. Another field of application of multiport converters can be power supply units for medical equipment. To increase the reliability of medical equipment, it is beneficial to use batteries as a backup supply, in case of failures in the main power source. Also, modern medical equipment can have several functions, and different loads may require different characteristics of input voltages and currents. As an example of such modern medical equipment there is a surgical lighting system with adjustable positioning of reflector during the operation of the system. Such a luminaire requires different voltage levels for different system parts (LED drivers, control unit, sensors, etc.). Considering the necessity of adding backup power supply, the most suitable solution is the application of multiport converter. This paper deals with the initial evaluation of partially isolated multiport converter with the help of Matlab-Simulink model.

Advanced Adiabatic Compressed Air Energy Storage (AA-CAES) is becoming increasingly attractive in power generation applications, whereby compressed air released from an artificial storage is preheated via sensible heat exchange and injected into an air turbine to generate electricity. Likewise, Latent Heat Storage (LHS) systems incorporating Phase Change Materials (PCM’s) are gaining popularity due to their advantages over the conventional sensible heat transfer systems. Therefore, combining these two forms of energy storage technologies appears to have great potential. Nevertheless, not enough technical literature is available on this combination when implemented in electrical power systems. To this end, this paper combined the use of the AA-CAES and the PCM-LHS systems and coupled them to a gas turbine and an air turbine, in an attempt to assess and compare the resulting overall system performance. The simulation results showed that a CAES volume reduction by 44% on average and thereby lower investments costs would be expected when the combination is coupled to a gas turbine, despite the seemingly higher roundtrip efficiency obtained when coupled to an air turbine. It was also concluded that the fuel consumption of the gas turbine is reduced by 50% on average when the compressed air is preheated via the PCM-LHS system instead of the gas turbine’s exhaust heat recovery system.

One of the effective options to achieve higher power density and lower-weight electric motors for electric vehicle (EV) applications is to replace the conventional winding with a hairpin configuration. This novel concept has several advantages, but the biggest drawback is high AC loss. Therefore, as this type of winding utilizes in EV motors for high-speed application, the correct estimations of this loss are essential during the design procedure. This paper presents three primary approaches to model and calculate the AC loss of hairpin windings: analytical, hybrid model, and FEA methods. In addition, the FEA method is used to validate and evaluate the accuracy of two other methods. Accordingly, both analytical and hybrid model results agree with FEA results. However, the hybrid model has higher accuracy rather than the analytical method.

In view of the increasing demand for the short-term load forecasting accuracy of commercial buildings, in order to overcome the data shortage, so that the subsequent forecasting model can learn the characteristics of the original data set more fully, and extract the effective characteristics of the data better, this paper proposes a short-term load forecasting method based on the hybrid model of TimeGAN generative adversarial network and CNN-LSTM Network. Firstly, the TimeGAN network is used to generate synthetic data to expand the scarce data set. Then, the CNN network is used to filter the input data and extract useful information, and the LSTM network is used to analyze and forecast the time series data. The proposed method calculates the power load data of a company in Shanghai for two months. Compared with CNNLSTM model and LSTM model which do not use synthetic data, the obtained short-term power load forecasting results improve the forecasting accuracy.

The new Italian standard CEI 0-21 allows the choice about single-phase or three-phase connection to the Distribution System Operator (DSO). This applies to Photovoltaic Systems (PVSs) with power up 10 kW. Single-phase connection to the grid is adopted for power below 6kW. Differently, both single-phase connection and three-phase connection are possible in the range [6–10] kW. Single-phase transformer-less DC/AC converters can exhibit some issues about the compliance with safety requirements. As the transformer-less inverters market is becoming more competitive, the aim of this paper is to benchmark some single-phase transformer-less DC/AC converters providing a fair comparison. The performances are evaluated considering leakage current, reactive power handling capability, power quality, filter and power converter rating.

An Electronic Capacitor (EC) is a bidirectional DCDC converter that utilizes a small auxiliary capacitance and mimics the low-frequency behavior of a different (typically much higher) capacitance. The well-known problem of using the electronic capacitor as an alternative to an electrolytic one is its poor ability to withstand step load changes. This paper proposes a novel approach to achieve better dynamic behavior of an EC, improving its ability to withstand sudden load changes while maintaining total harmonic distortion (THD) and DC-link voltage undershoot (US) standards of the grid. PSIM simulations are presented to support the validity of the proposed methodology.

The proposed architecture takes advantage of active filtering and partial power processing to achieve a cost-effective and efficient implementation. The proposed converter has been analyzed, simulated, and designed, and it will be tested using a 50-kW upwards-scalable module.
