“…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.

A pulse-width-modulation (PWM) bidirectional ac-dc converter (i.e., active rectifier) with dc-faultblocking and self-pre-charge capabilities is proposed in this paper for low-voltage dc (LVDC) applications. The proposed converter, which is named as "H5 + converter", consists of an H4 bridge, a bidirectional switch, and a transient-voltage-surge (TVS) diode. The bidirectional switch and the TVS diode enable the dc-fault blocking and dc-bus self-pre-charge, while preserving the low common-mode voltage noise and low leakage current of the converter. Additionally, the proposed H5+ converter has advanced features under a dc-side short-circuit fault, such as fault diagnosis and fault recovery. Operation principles of the proposed converter are presented and analyzed. A down-scaled prototype is built.Experiment results are shown and analyzed, including steady-state waveforms, common-mode performance, start-up dynamics, as well as dc fault blocking, fault diagnosis, and fault recovery. Moreover, the proposed converter is compared with other two dc-fault-blocking converters for LVDC applications, in terms of converter capabilities, required devices, and power switch losses.
