Integrated Full-Bridge-Forward DC–DC Converter for a Residential Microgrid Application

Abstract

This paper proposes a novel integrated converter topology for interfacing between the energy storage system and the DC bus for a residential microgrid application. The proposed integrated full-bridge-forward DC-DC converter presents the following features: low number of active devices compared to the converters usually applied to similar applications, low input and output current ripple, high voltage ratio, bidirectional power flow, and galvanic isolation. A double-ended forward converter with particularities such as no extra transformer demagnetizing circuit is originated from the integration process. This converter is approached in detail in this paper, including three different clamping circuits which are analyzed and compared. The structure, principle of operation, analysis, transformer design methodology, comparison with the dual active bridge converter, and experimental results of the proposed topology are presented.Index Terms-DC bus interconnection, DC-DC converter, energy storage system, static power converter integration.

Jaya based Optimization Method with High Dispatchable Distributed Generation for Residential Microgrid

“…An ESS is attached to an inverter which is used to convert DC to AC for electricity transmission. A novel inverter for energy storage is proposed in [36,37]; the inverter is used to minimize the burden on the MG. However, the authors only considered the performance of practical DC and AC with ESSs, whereas energy exchange was not considered.…”

Enhanced torque control in a DFIG connected to a DC grid by a diode rectifier

“…Such systems are being studied and applied in recent years, thanks to the development of power electronic apparatus [4]- [5]. The connection of an ac generator to a dc-bus can be obtained in several ways.…”

Evaluación analítica y experimental de un convertidor cc-cc aislado apto para sistemas fotovoltaicos

“…Muchas veces están conformados por dos etapas, donde la primer etapa es un convertidor tipo boost, encargado de elevar la tensión a un valor superior a la máxima tensión de entrada, el que alimenta con una tensión constante a la segunda etapa, encargada de proveer la aislación requerida por el sistema [1] [2]. Ambas etapas deben procesar la totalidad de la potencia de entrada, lo que va en demérito de la eficiencia.…”
