The high potentiality of integrating renewable energies, such as photovoltaic, into a modern electrical microgrid system, using DC-to-DC converters, raises some issues associated with controller loop design and system stability. generalized state space average model (GSSAM) concept was consequently introduced to converter in order evaluate performance conduct stability studies. This paper prese...

Abstract−This study mainly focuses on the development of an automatic fuzzy control (AFC) system for a parallel dc-dc converter, and the control objective is to achieve the stable voltage regulation and uniform current distribution. The average model for an example of a three-module boost converter, which is composed of three conventional boost converter frames in parallel connection, is derive...

This paper describes a classification of paralleling schemes for dc–dc converters from a circuit theoretic viewpoint. The purpose is to provide a systematic classification of the types of parallel converters that can clearly identify all possible structures and control configurations, allowing simple and direct comparison of the characteristics and limitations of different paralleling schemes. ...

an automatic fuzzy control (AFC) system for a parallel dc-dc converter, and the control objective is to achieve the stable voltage regulation and uniform current distribution. The average model for an example of a three-module boost converter, which is composed of three conventional boost converter frames in parallel connection, is derived for the design of this AFC system including voltage and...

This paper investigates the effect of temperature on a hybrid energy storage system with various energy management systems. The hybrid energy storage system consists of a fuel cell, ultracapacitor and battery with associated DC/DC and DC/AC converters. The energy management strategies employed are the state machine control strategy, fuzzy frequency/logic decoupling strategy, minimization strate...

In this paper, a DC-DC resonant converter with high voltage gain and small size is studied. To reduce the size and weight of this converter, the operating frequency should be as high as possible. In this research, the frequency changes from 120 to 200 kHz. Due to the high operating frequency, it is necessary to reduce the switching losses using soft switching methods. Resonant converters are su...
