Soft switching topologies have become popular in many applications in the last twenty years. The most popular soft switching technology, the LLC topology is not suitable for a larger input-output voltage range necessary in many applications such as battery charges, though some complex
solutions were recently proposed.
The latest developments in semiconductor technologies such as SiC and GaNs devices have
facilitated the soft switching operation. The ultra-low impedance of the latest semiconductor
devices has also created the opportunity for new magnetic technologies.
The goal of this seminar is to present new soft switching technologies which can be applied to
any of the classical hard switching topology converting them to a “true soft switching topology”. In “true soft switching topology”, the primary switching devices turn on at zero voltage and the
secondary switching devices turn off at zero current. There is no ringing or spikes across any of the switching devices in primary or secondary. Unlike LLC topologies the new technologies can efficiently operate for an output voltage range of 6:1, and a total input-output voltage range of
18:1 for power delivery 3.0 and 3.1. The seminar will also present several new magnetic
technologies suitable with these new soft switching topologies for higher output power for
Automotive with very high efficiency for isolated DC-DC converters. Very informative for
engineers working in Automotive for high power chargers including bidirectional
chargers and also for lower power applications such as ultra-high-density AC-DC
adapters in compliance with P.D. 3.0 and 3.1.
Who should attend?
Electrical engineers, magnetic engineers, and engineering managers in the power conversion field, with application in Automotive, industrial and consumer product. Students in power electronics are also welcomed.

The tremendous progress in semiconductor technology moved the spotlight for very high efficiency quest towards the magnetics. A study of the loss mechanism in the magnetics and ways to improve it, together with Novel magnetic structures will be presented. The
seminar will present in detail all the parasitic elements in the magnetics, the loss
mechanism associated with it and solutions in addressing them. This section will be also highlighted with design examples in application wherein the power conversion efficiency reached 99%. Another section of the seminar will be dedicated to magnetic integration. It will start with Quasi-Integrated Magnetic wherein the main transformer becomes a partial energy storage reducing the size of the output filter. This concept can lead to great
optimization of the power train efficiency. The presentation will continue with the
“multi-legged” magnetic configuration, which is the latest magnetic technology today,
referred also as “ultra-planar” magnetic. Other forms of distributed magnetic structures
will be presented, some of them in power converters with the highest power density and lowest profile on the market. Another chapter is dedicated to wireless magnetic
structures, with experimental data and examples ranging from power level of 10W to
1KW wireless applications. Very informative for engineers working on increasing the
efficiency and power density in high power chargers in Automotive power converters to the ultra-high-density AC-DC adapters.
Who should attend?
Electrical engineers, magnetic engineers, and engineering managers in the power
conversion for Automotive, Industrial and Consumer field. Students in power electronics are also welcomed.
