153. MathCityMap@home Digitale Lernpfade mit gestuften Hinweisen und synchroner Schüler-Lehrer-Interaktion

Author

Barlovits, Simon, Jablonski, Simone, Milicic, Gregor, and Ludwig, Matthias

Abstract

Homeschooling in der Corona-Krise stellt Lehrende und Lernende vor neue Herausforderungen. Insbesondere die Unterstützung der Lernenden durch Hilfestellungen und die Überprüfung von Lösungen und Lösungswegen scheinen besonders herausfordernd. Ursprünglich als Lernumgebung für außerschulische Lernorte entlang mathematischer Wanderwege konzipiert, kann das MathCityMap-System während der Corona-Krise auch Lehrkräfte beim Online-Mathematikunterricht durch das MathCityMap@home-Konzept unterstützen. Hinweise, eine unmittelbare Validierung der Eingaben und die Bereitstellung einer Musterlösung unterstützt die Schülerinnen und Schüler beim asynchronen Lernen. Innerhalb des Digitalen Klassenzimmers ist es zudem möglich, die Ereignisse während des Bearbeitungsprozesses der Schülerinnen und Schüler unmittelbar nachzuvollziehen. Der Chat kann für eine synchrone Interaktion genutzt werden, sodass die Lernenden individuell unterstützt werden können. Im Beitrag stellen wir die Anwendung des MathCityMap@home-Konzeptes anhand eines authentischen Beispiels vor.

170. Packaging and integration technologies for future high-frequency power supplies

Author

Mathuna, Sean Cian O., Byrne, Patrick, Duffy, Gerald, Chen, Weimin, Ludwig, Matthias, O'Donnell, Terence, McCloskey, Paul N., and Duffy, Maeve

Subjects

Abstract

This paper reviews data from the International Technology Roadmap for Semiconductors to establish where dc-dc converters are headed in the first decade of the new millennium. It focuses on the high performance computing (high current, fast response, high power density) and portable/handheld (low profile) sectors. Magnetics and power device packaging technologies needed to allow power supplies to move to operating frequencies in the 1-10 MHz region are discussed. It introduces the concept of magnetic components fully embedded (windings and core) in PCB and silicon offering low profile and low losses at high frequency. It also reviews developments in wirebond-free power packaging such as flip-chip assembly that offer low profile, reduced parasitics and increased thermal performance. Finally, consideration is given to the changes in the power electronics industry that may need to be addressed to enable these new technologies to play a strategic role. Index Terms--Integrated magnetics, power packaging, power supplies, reviews, semiconductor device packaging.

171. PCB integrated inductors for low power dc/dc converter

Abstract

This paper discusses the use of printed circuit board (PCB) integrated inductors for low power dc/dc buck converters. Coreless, magnetic plates and closed core structures are compared in terms of achievable inductance, power handling and efficiency in a footprint of 10 x 10 [mm.sup.2]. The magnetic layers consist of electroplated NiFe, so that the process is fully compatible with standard PCB process. Analytic and finite element method (FEM) methods are applied to predict inductor performance for typical current waveforms encountered in a buck converter. Conventional magnetic design procedures are applied to define optimum winding and core structures for typical inductor specifications. A 4.7 [micro]H PCB integrated inductor with dc current handling of up to 500 mA is presented. This inductor is employed in a 1.5 W buck converter using a commercial control integrated circuit (IC). The footprint of the entire converter measures 10 x 10 [mm.sup.2] and is built on top of the integrated inductor to demonstrate the concept of integrated passives in power electronic circuits to achieve ultra flat and compact converter solutions. Index Terms--Electroplating, embedded PCB magnetics, integrated magnetics, low power conversion, magnetic design study, ultra flat inductors.
