Investigation of Novel Transformerless Converters for DC Microgrid: Design and Analysis

A Feedback Passivation Design for DC Microgrid and Its DC/DC Converters

Abstract: There are difficulties in analyzing the stability of microgrids since they are located on various network structures. However, considering that the network often consists of passive elements, the passivity theory is applied in this paper to solve the above-mentioned problem. It has been formerly shown that when the network is weakly strictly positive real (WSPR), the DC microgrid is s...

Analysis and design of DC/DC converters using symbolic approach

An MS-DOS personal computer program for the analysis and design of DC/DC converters is presented. The program, named SPAC (Symbolic Program for Analysis of DC/DC Converters), is based on symbolic analysis techniques and is able to calculate automatically, starting from a graphical schematic entry, the circuit s-domain network functions in a completely symbolic form. By means of suitable algorit...

Design of Automatic Fuzzy Control for Parallel DC-DC Converters

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...

Analysis and Design of EMI Filters for DC-DC Converters Using Chain Parameters

Switch-mode power converters (SMPCs) are known as one of the greatest sources of electromagnetic interference (EMI) in electronic equipments. In order to comply with the strict electromagnetic compatibility (EMC) requirements, an EMI filter is needed at the input of a SMPC. The design of EMI filters aims at achieving required insertion loss (IL), i.e. attenuation of the power of the unwanted el...
