In this paper utilization of a boost converter for control of photovoltaic power using Maximum Power Point Tracking (MPPT) control mechanism is presented. First the photovoltaic module is analyzed using SIMULINK software. For the main aim of this work the buck converter is to be used along with a Maximum Power Point Tracking control mechanism. The MPPT is responsible for extracting the maximum ...

This paper presents a power supply module targeted for low-power applications in the sub-mW range incorporating a passive μDMFC fuel cell (μFC) acting as energy source and a customized boost converter for the energy conversion. The low power budget of such energy sources mandates the adoption of efficient circuit solutions, hence the design of the boost converter is challenging. To maximize the...

EWEE include following parts: GUARD and Driven-Right-Leg (DLR) systems [2, 3, 6]. First system protects wire connections (on PCB, silver contacts with differential amplifier) against electromagnetic influence. The second provides better Common Mode Rejection Rate (CMRR) coefficient in range of 20-50dB higher. Another parts of system are: silver contacts [5], instrumentation amplifier with perma...

This thesis focuses on the study, implementation and improvement of a digital controller for a power factor correction (PFC) converter. The development of the telecommunications industry and the Internet demands reliable, cost-effective and intelligent power. Nowadays, the telecommunication power systems have output current of up to several kiloamperes, consisting of tens of modules. The high-e...

System integration is one of the market driving issues in power electronics. In this paper the integration of precise shunts into IGBT modules, like it is done in Infineons MIPAQ family, is compared to on-IGBT-chip current sense functionality. Temperature measurement via NTC-resistor on DBC-level or on-IGBT-chip integrated temp-sense-diodes will be treated as well. Further processing of the low...

Abstract: Currently, the auxiliary converter in the auxiliary power supply system of a modern tram adopts Si IGBT as its switching device and with the 1700 V/225 A SiC MOSFET module commercially available from Cree, an auxiliary converter using all SiC devices is now possible. A SiC auxiliary converter prototype is developed during this study. The author(s) derive the loss calculation formula o...

Converter transformers are the key and the most important components in high voltage direct current (HVDC) power transmission systems. Statistics show that the failure rate of HVDC converter transformers is approximately twice of that of transformers in AC power systems. This paper presents an approach integrated with a two-dimensional cloud model and an entropy-based weight model to evaluate t...

various methods for parametric interpolation of nurbs curves have been proposed in the past. however, the errors caused by the approximate nature of the nurbs interpolator were rarely taken into account. this paper proposes an integrated look-ahead algorithm for parametric interpolation along nurbs curves. the algorithm interpolates the sharp corners on the curve with the pythagorean-hodograph ...

In this dissertation an integrated approach to formal module verification by model checking andmodule testing is described. The main focus lays on the verification of C functions. Specification-based testing and functional verification require a formalized module specification. For this purposean annotation language as an extension of a pre-/post-condition syntax is developed and di...
