This paper presents a new Power Electronic Building Block (PEBB) designed to facilitate the implementation of different power converter topologies. The proposed PEBB consists of two diodes and two transistors and it can be used to implement the most relevant power converter topologies, due to its modularity. The addition of the two diodes is an exclusive feature of the new PEBB, which permits t...
In this paper, a 24-pulse ac-dc converter is designed, modeled and simulated based on a fork autotransformer to improve power quality indices. The use of autotransformer results in reduced kVA rating of the proposed topology as compared with the transformer based 24-pulse converter. Due to the proper flexibility of the proposed topology, it can be simply utilized in other similar applications. ...
Grid-tied power electronic converters are key enabling technologies for interfacing renewable energy sources, storage, electrical vehicles, microgrids, and high-voltage dc transmission lines with the grid. As number of in modern grids continually increases, their monitoring coordinated control a way to support grid have become topics increased practical research interest. In connection this, la...
The increasing penetration of distributed and renewable generators into today’s power systems poses new challenges to power system management and control. Future power system management systems have to balance the mismatch between volatile renewable generation and load as well as to bridge the geographical gap between renewable generators and load centers. For power system modeling, analysis an...
Sigma delta modulators (ΣΔMs) form part of the core of today’s mixed-signal designs. They are cornerstone components of oversampled data converters. Such data converters take advantage of digital signal processing techniques and VLSI technology to provide high performance with low sensitivity to analog component imperfections and noisy conditions. The ongoing research on these devices shows the...
The importance of effective energy conversion control, including power generation from renewable and environment-friendly energy sources, has increased due to rising energy demand. Power electronic systems for controlling and converting electrical energy have become the workhorse of modern society in many applications, both in industry and in the home. Power electronics plays a very important r...
This paper focuses on two key technical concepts, which may have a tremendous impact future generations of power electronic converters: the Power Electronic Building Block (PEBB) concept, and 5G/6G wireless data transfer. It is expected that these trends induce development new cognitive Electronics 4.0. To investigate this Proof Concept (PoC) PEBB-based converter integrated with 5G network, was...
High performance high bandwidth control of power electronic converters, inverters, and motor drives has become feasible over the past decade. These devices behave as constant power loads over large bandwidths when they are tightly regulated. However, constant power loads have a severe side affect known as negative impedance instability. In order to mitigate the problem of negative impedance ins...
