Education should not suffer from the COVID-19 pandemic. The lockdown has unabled the organization of on-site trainings in 2020 and it is still the case today. On top of that, the COVID-19 pandemic is still affecting the economy and impacts the investment priorities within companies such as the financing of professional training courses.
In this context and with the willingness to strengthen power electronics professional skills, Powersys will exceptionally offer this course to 10 attendees (7 industrial customers and 3 academic customers).
Don’t wait too much to register! First-come, first-served!
Number of seats max.: 10 including 7 seats for Industry and 3 for Education.
Resonant power converters, especially those with an LLC- configuration, are receiving renewed interest in automotive and aerospace industries because of the potential of these converters to achieve both higher switching frequencies and lower switching losses. Design of a LLC converter is a challenging task, and requires more effort for optimization compared to traditional PWM converters. This e-training aims to give the participants the tools to be able to optimally design the converter.
This training is especially designed for individuals and professionals who wants to get into the converter design aspects as well as for people who wants to build their own hardware.
This training covers the basics of each topic but it can be considered as mid-level to high-level course focused in the following specific objectives:
Basic principle of resonant converters like SLLC, LLC, DAB.
Understand how LLC converter works and how it can be modelled using various design techniques.
Know how to derive an equivalent circuit model and solve for the converter efficiency
Provide a complete set of practical reference designs (PSIM simulation examples, SmartCtrl design examples) for the main LLC converter applications.
Learn how to design a power stage and control stage like pro
Provide real life examples of LLC converter from industry leaders and tricks
Understand how to implement the SiC power semiconductor devices in a switching converter
Gate driver design aspects of the Si and SiC devices
Learn how to design gate driver hardware and practical tips
Know more about thermal modelling and heat –sink design
The e-training is recommended for anyone who is interested in learning theoretical and hardware design aspects of a LLC based resonant converter. Only basic knowledge in power electronics will be enough to take part in the training.
The training is ideal for:
The practicing engineer (firmware and power hardware engineers) will be given with the physical meaning and efficient explanations about the power stage design, modeling and control problem.
The university student (Master and PhD degrees) will find easy-to-follow mathematical developments not always covered in the text books.
Instructors and university professors will find a different approach for their explanations as well as an interesting set of simulation reference designs.
The power hardware and control expert are also invited to participate in a discussion-space to share practical experiences on specific problems.
The focus is placed on Concepts
The explanations are focused on the concepts and physical meaning. Mathematical developments are also included as reference materials in annexes.
Controller design using SmartCtrl + PSIM simulation to test the results.
Examples & Exercises
A large number of examples are used to show training explanations.
Exercises are proposed to be developed by the audience during the training.
SmartCtrl files and PSIM files are provided in advance to develop efficiently the examples and exercises.
No of hours: 10 hours broken into 2 days
Temporary PSIM license: PSIM temporary licenses will be provided for the duration of the course.
Computer: Each participant will have to bring a personnal computer.

Sumantra Bhattacharya studied Engineering Cybernetics and received his B.Sc degee from Jadavpur University and M.Sc. degree in 2017 from the RWTH Aachen University. He has worked with companies like Caterpillar, Astec Industries, Mitsubishi Electric Japan etc. Since 2018, he is working in Institute for Energy Conversion and Storage (EWS) for development of power electronic converters for fuel cell driven aircraft in association with German aerospace (DLR). He is also a doctoral candidate at the Institute for Energy Conversion and Storage (EWS) at University of Ulm. His research focus lies in the modelling, control and design of high power density novel power converter for full electric aircraft.
