18/09/2017 - 19/09/2017 - ECPE Workshop: Power Supplies in Low Power Applications

Prof. Giorgio Spiazzi, University of Padova
Dr. Manfred Schlenk, Infineon Technologies
Dipl.-Ing. (FH) Jochen Koszescha, ECPE

During the last years new emerging applications just as IoT as well as the size reduction of electronic equipment have driven new requirements for power supplies up to several hundred watts. Power density, operating efficiency as well as standby power are becoming more and more important. Therefore exiting topologies have been modified, new topologies have been developed and advanced control methods have been implemented always considering the cost aspect.

One of the enabling technologies for all of this was digital control. The use of digital controllers or microprocessors becomes now more and more common. It is recognized, that i.e. load and input voltage dependencies on the operationally efficiency, parameter variation can be optimized in an easier way than with analogue control.

The workshop will cover power conversion systems for lighting, consumer and household applications. Concepts for increasing operational efficiency and decreasing standby power will be shown. So i.e. high efficient soft switching strategies for high density flyback converters will be explained. Advanced control concepts for LLC and PFC power stages will be shown.

Besides solutions for highly efficient AC/DC converters also low voltage DC/DC converters will be presented. The latest trends for these kind of converters will be shown. Control methods just like adaptive control will be explained.

All presentations and discussions will be in English language.
