Electric energy converter development and diagnostics in mixed-signal simulation environment

Abstract

<p class="Abstract"><span lang="EN-US">In this work the input and output capacitors of a digitally controlled Buck converter have been tested in 4 different cases with unused and worn out capacitors. The information extracted from interactions between the subsystems of an electric energy conversion system requires the implementation of the whole system from network to load. A complex simulation environment has been implemented where digital and analogue domains can be connected. The input and output capacitor aging have a significant influence on time domain characteristics, but the evaluation of frequency-domain data is supposed to be required to extract information from the noisy and distorted time-domain signal. The presented diagnostic approach aims to analyze signals that are used by the control loop in order to avoid expensive additions to existing circuits.</span></p>

Concept of a Reliable Redundant Off-grid Power Supply Chain

“…The quality of the converter significantly determines the capabilities and efficiency of the system. [3] Grouping could be further listed, but it would go beyond the bounds of this article, therefore we are confined to the most important ones.…”

Modeling of Autonomous EV Vector-Controlled Power Conversion System for Battery Management System Design

“…In the early phase of development, the testing and design of these systems should be performed simultaneously to take advantage of the interconnected simulation environment. A mixed-signal simulation environment supports the analysis of controlled electric power conversion systems where digital and analogue domains * Correspondence: kohlrusz.gabor@mk.uni-pannon.hu can be connected and run simultaneously [1]. Simulations can be performed by taking into account practical aspects that introduce cycle times and delays into the model.…”
