With the benefit of high power density and bidirectional multi-input multi-output (MIMO) power transfer capability, the multiport active bridge (MAB) topology has been widely used in the electric transportation onboard propulsion and charging systems. However, the nonlinear power transfer behavior brings challenge to its control system design. As the dynamic performance of the traditional proportional-integral (PI) controller is characterized by a relatively slow response and large overshoot. To address this issue, decoupling control strategies have been proposed to enhance the transient response and control flexibility of the system. This paper discussed and compared several nonlinear decoupling control methodologies including the small signal state-space linearization based and optimization algorithm based decoupling control. Simulation verifications are performed to conclude the suitable applications.

Due to current limitations of semiconductor modules there is necessity of paralleling for higher power achievement. On the one hand particular transistors in one converter can be paralleled providing one of the simplest and cheapest approach. On the other hand, numbers of converters can be paralleled giving an opportunity for diversification power, improved reliability and converter maintenance [1], [2]. In other words, the power can be increased by adding another device to a system. Additionally, for low load, some of the converters can be switched off from a grid to achieve higher efficiency. For AC-DC converters zero-sequence voltage component of $3^{text{r}text{d}}$ harmonic is often applied due to increase power capability. However, for non-isolated parallel converters, this approach causes additional equalizing current flow that circulate between converters. A compensation technique for that issue is proposed by adding additional neutral current controller as well as common zero-sequence voltage factor for all parallelly connected converters.

This paper introduces a novel design for a power factor correction (PFC) integrated flyback transformer, which aims to enhance line harmonic current and common-mode noise reduction. The design includes two stages, a PFC stage with two boost inductors and a flyback stage utilizing a flyback transformer. The integrated flyback transformer has a curved air gap solution to prevent core saturation and enhance transformer efficiency. The study presents simulation and experimental results obtained from a prototype circuit of 270W (32.5V/8A) with 4 ferrite materials (3C92,3F35, 3F45 and 4F1).

This paper proposes a new buck-boost flying-capacitor (FC) converter for the DC-DC stage of an Electric Vehicle (EV) fast charging station. The proposed converter is capable of delivering a wide output range of voltage to charge different battery configurations. The converter has two modes of operation, buck and boost. Thanks to this feature, the proposed converter allows higher efficiency and a wide operating range. The proposed converter is capable of supplying a voltage range from 200 V to 1000 V at its output, which shows the feasibility of occupying the converter inside a charging station that allows charging 400 V and 800 V battery systems. The average efficiency reported is over 97%. It is concluded that the proposed buck-boost FC converter is suitable for modern wide-output EV fast charging applications.

Hybrid distribution transformers (HDTs) integrate a power converter with a conventional transformer, improving power quality and providing ancillary services. When the series converter is connected to the primary side, it is possible to use this converter to regulate the load voltage. Nonetheless, if there is no proper care in how the voltage is injected, there is a risk of producing a DC offset on the flux of the main Low-Frequency Transformer (LFT). In that case, the transformer can generate inrush currents. The latter can damage equipment and trigger security systems. This work presents an HDT connected in series to the medium-voltage grid through Coupling Transformers (CTs). The series converter is used to regulate the flux of the main LFT to its rated value and indirectly regulate the load voltage. A flux regulator and a simple flux estimator are presented. Results show that the series converter can successfully regulate the distribution transformer flux, controlling the inrush current and removing the magnetic flux offset from the CTs.

Transformerless photovoltaic (PV) inverters are more effective, lighter in weight, and less expensive than transformer-based topologies. However, a leakage current $(i_{Leakage})$ is produced when transformers are removed due to the direct connection between the PV panel and the grid. This current reduces the life of the insulation, causes safety problems, and increases the harmonic distortion in the grid current. To overcome these issues, an improved three-phase transformerless neutral point clamped (NPC) topology is proposed by employing two additional switches on the primary side of a traditional NPC inverter. This arrangement reduces the iLeakage significantly and improves the harmonic behavior of the grid current by operating the additional switches in zero switching states. Furthermore, when compared to a conventional H8 inverter, its multilevel capability reduces voltage stress on semiconductor devices. Finally, the proposed topology is validated with the help of the Simulink model in MATLAB by comparing it to a traditional three-phase H8 inverter, considering $i_{Leakage},$ common-mode voltage (CMV), and the grid current total harmonic distortions (THD).

Energy management strategies directly influence the performance (e.g., cost) of residential PV systems. In state-of-the-art, most forecast-based energy management strategies adopt hour resolution to make decisions, which may have poor robustness and flexibility to fast-changing weather conditions. This paper compares the sensitivity of three typical operation strategies including maximum self-consumption, mixed integer linear programming, and particle swarm optimization under different kinds of resolutions and weather. The results show that the maximum self-consumption strategy has the best robustness and can utilize the battery most at the expense of total cost. In terms of cost, the mixed integer linear programming strategy performs best on the sunny day, and has the best scheduled result on the partly-cloudy day, but the particle swarm optimization strategy performs best in the real case.

This paper presents a novel approach based on random variable algebra to study the neutral current ripple in three-phase four-wire split-capacitor inverters. The proposed method provides a more intuitive way of understanding and quantifying current ripple cancellations occurring on the neutral wire. Furthermore, thanks to its more straightforward approach, the extension over the whole modulation index range of neutral current ripple RMS in the case of interleaved PWM is presented. Finally, a comprehensive analysis of the neutral current ripple RMS in the case of unevenly displaced PWM carriers is also discussed. All the developments are validated by employing numerical results tested over various operating conditions.

This article presents a concept of the control algorithm for an advanced fast charging system for electric vehicles with battery energy storage. Such a system consists of an AC/DC grid converter, isolated DC/DC converters for slow and fast vehicle charging, and a non-isolated DC/DC converter ensuring bi-directional energy flow between the storage and other converters of the system. All the components are connected via a bidirectional DC bus. They have to be controlled by the main unit due to the complex structure of the system. Several possible operating modes and control signals are analyzed, ensuring the safe and correct operation of the system, and the following converters are proposed. In addition to the analysis, simulation results are presented in the study to confirm the proper system operation.
