“…Possui tal denominação por ser composta de elementos ativos (chaves) e elementos passivos (capacitores). Diferentemente do realizado por (Wang et al 2012), (Amin et al 2015), (Chakraborty;Chattopadhyay 2017), (Han et al 2018), (Xiangli, et al 2018), (Wu et al 2019), (Shi et al 2020), que empregam a modulação Phase-Shift para a operação do conversor DAHB, este artigo propõem o uso de modulação PWM simétrica para a comutação das chaves.…”

Este trabalho apresenta um sistema de interconexão de múltiplas fontes para geração de energia em microrredes. O sistema baseia-se no uso de uma fonte CC primária de energia (neste caso, geração fotovoltaica) combinada com um sistema básico de geração de CA, sendo, nesse caso, um gerador de indução auto excitado (GIAE), além de um sistema de armazenamento de energia da bateria (ESS). A integração de múltiplas fontes é realizada por meio do conversor bidirecional isolado de Dual Active Half-Bridge (DAHB). O conversor DAHB é responsável pela interface entre as fontes de energia, bem como no gerenciamento do fluxo de potência entre o barramento primário e secundário. O sistema proposto possui três barramentos de tensão, sendo um barramento trifásico a quatro fios derivados de um DSTATCOM em que as cargas estão conectadas e dois barramentos CC, sendo os barramentos primário e secundário do conversor DAHB. Neste trabalho, é desenvolvida a modelagem matemática do conversor DAHB de maneira simplificada, a partir da qual o projeto dos controladores é realizado. Além disso, são apresentados resultados de simulação e experimentais acerca do conversor DAHB, validando este e os controladores projetados.

“…In [12], a state-space averaging model has been proposed for a bidirectional converter. For DC-DC converters with pulsating output current, such as boost converters, the use of leading-edge or trailing-edge pulsewidth modulation (PWM) brings about distinctly different behavior [13]. is phenomenon cannot be captured by the conventional averaged model but is predicted with a discretetime model.…”

Utilization of renewable energies in association with energy storage is increased in different applications such as electrical vehicles (EVs), electric boats (EBs), and smart grids. A robust controller strategy plays a significant role to optimally utilize the energy resources available in a power system. In this paper, a suitable controller for the energy resources of an EB which consists of a 5 kW solar power plant, 5 kW fuel cell, and 2 kW battery package is designed based on the linear parameter varying (LPV) controller design approach. Initially, all component dynamics are augmented, and by exploiting the sector-nonlinearity approach, the LPV representation is derived. Then, the LPV control method determines the suitable gains of the states’ feedbacks to provide the required pulse commands of the boost converters of the energy resources to regulate the DC-link voltage and supply the power of EB loads. Comparing with the state-of-the-art nonlinear control methods, the developed control approach assures the stability of the overall system, as it considers all component dynamics in the design procedure. The real-time simulation results demonstrate the performance of the designed controller in the creation of a constant DC-link voltage.

“…Based on the phase shifted converter applications, phase shift pulse width modulation (PWM) converter can be implemented using different switching schematics (full bridge, half bridge, dual half bridge) in primary and secondary sides, and analysis of phase shifts isolated DC-DC converter different topologies previously given in [11]. Analysis and design of phase shift controller for a dual half bridge DC-DC converter is provided in [12]. Based on the application of DC-DC converter, it can be designed as an isolated or non-isolated converter; for the isolated DC-DC converter, transformer design and choice are a big challenge to have ZVS for the wide range of the load, which can reduce the switching and conduction losses [13].…”

This paper presents a complete mathematical design of the main components of 2 kW, 54 direct current (DC)–DC converter stage, which can be used as the second stage of the two stages of alternating current (AC)–DC telecom power supply. In this paper, a simple inrush current controlling circuit to eliminate the high inrush current, which is generated due to high input capacitor at the input side of the DC–DC converter, is proposed, designed, and briefly discussed. The proposed circuit is very easy to implement in the lab using a single metal–oxide–semiconductor field-effect transistor (MOSFET) switch and some small passive elements. PSIM simulation has been used to test the power supply performance using the value of the designed components. Furthermore, the experimental setup of the designed power supply with inrush current control is built in the lab to show the practical performance of the designed power supply and to test the reliability of the proposed inrush current mitigation circuit to eliminate the high inrush current at initial power application to the power supply circuit. DC–DC power supply with phase shift zero voltage switching (ZVS) technique is chosen and designed due to its availability to achieve ZVS over the full load range at the primary side of the power supply, which reduces switching losses and offers high conversion efficiency. High power density DC–DC converter stage with smooth current startup operation, full load efficiency over 95%, and better voltage regulation is achieved in this work.
