This paper describes a new methodology for the modeling and analysis of three-phase synchronous generators operating under an unbalanced regime. For this, an improved state model has been developed in order to determine significant signatures on stator and rotor electromagnetic quantities. This methodology is characterized by some advantages. Firstly, it can be generalized for the modeling of severe defects like open-phase and short circuits. Furthermore, by comparison to classical approaches based on the finite elements and symmetrical components methods, this approach gives a good compromise between precision and simulation time. The obtained results show the effectiveness of this approach for the analysis of unbalanced synchronous generators.

This paper introduces a LCL filter design tailored for a 40 kW three-phase grid-connected converter utilized in electric vehicle onboard fast chargers. In contrast to conventional filters, the LCL filter finds extensive application in AC/DC converters for power factor correction, thanks to its enhanced harmonic reduction and improved stability of the system. The parameters of LCL filter are devised based on considerations such as the system’s power, the frequency of the alternating current (AC) input, and the PWM frequency, determined through simulation and comprehensive theoretical analysis. By implementing a dual-current closed-loop control strategy, the system ensures a robust response for both the current on the AC side of the converter and the voltage on the direct current (DC) side. The analysis of the system’s performance includes rapid dynamic response, system efficiency, AC current harmonic, and DC ripple voltage. Both simulation and experimental results are presented to validate the proposed design for the LCL filter.

At present, energy storage systems are being generalized due to the necessity of providing stable and good-quality electrical service in all homes. Solutions are given to Ecuador's electrical power system using distributed generation facilities with different renewable energy sources. However, some of those facilities in the Province of Manabí are located relatively far from the power consumption areas, causing an energy deficit in some electrical feeders when demand increases. The objective of the present study is to analyze the functioning of an electrical feeder when energy storage systems and photovoltaic systems are connected as a hybrid system. Two different software, CYME, and ArcGIS, were used to analyze the electrical power system in the province object of study and to design the simulation that showed better functioning of the electrical feeder when energy storage systems are connected than with connection to photovoltaic systems.

Power electronics is a critical driver of innovation in industries like renewable energy, electric vehicles, and consumer electronics. While silicon (Si) devices have been dominant for five decades, escalating demands for higher power density expose limitations in terms of blocking voltage capacity, operational temperature, and switching frequency. Wide band-gap (WBG) materials, such as silicon carbide (SiC) and gallium nitride (GaN), offer compelling alternatives with low input capacitance, reduced losses, and excellent thermal characteristics. In addition, expanding electrical capabilities involves constructing an array of devices, such as series-connected power MOSFETs. This configuration offers advantages like higher blocking voltage, lower conduction losses, and reduced costs. This paper introduces the design of a fast-switching, stackable switching unit cell (SSUC) utilizing SiC MOSFET devices as power components. The SSUC facilitates the creation of versatile compound switches. To protect the power switch from harmful voltages and current spikes, the design incorporates both an active voltage clamp and a snubber with energy recovery. This feature extends the number of stages that can be connected in series. Experiments with a three-stage compound device, successfully tested at 3 kV, validate the practical applicability and flexibility of this concept.

This paper presents a computer simulation model for a high-power factor wireless DC power supply system, integrating an active power filter (APF) at the rectifier stage on the transmitter side using a rectifier boost technique. The APF, employing a MOSFET switch regulated by active pulse width modulation (APWM) within a current control loop, addresses pulsating and distorted AC supply currents caused by non-linear loads. A robust closed-loop control mechanism, including a subtractor circuit, proportional-integral (PI) controller, and comparator, ensures the generation of a continuous sinusoidal waveform synchronized with the supply voltage. The model utilizes a high-frequency inverter to convert DC to AC, which is then wirelessly transmitted via wireless power transfer (WPT) technology and converted back to DC by a high-frequency rectifier. MATLAB/Simulink simulation results show a significant reduction in total harmonic distortion (THD) of the AC supply current, complying with IEEE 519 standards. Selected results are presented to verify the proposed method's effectiveness in reducing harmonic distortions and enhancing power quality. This study highlights the advantages of WPT in scenarios where traditional wired connections are impractical and underscores the potential of this system for real-world applications, particularly in developing high-power factor wireless DC power supply systems.
