Le Meridien Hotel Seoul - April 12
The presentations will benefit product developers who have at least basic understanding of magnetic induction. It is not intended for novices. The concepts have medium complexity and will benefit product developers who design wireless power products using existing chipsets and one of the standard transmitter designs.
|9:00||Qi Certification - compliance testing, interoperability testing and common pitfalls||Menno Treffers||Chairman, The Wireless Power Consortium|
|The rapid growth of wireless charging adoption has led to many low-quality, counterfeit products that are potentially unsafe.
Products using the Qi standard must be tested rigorously to help ensure safety, interoperability and energy efficiency. Only products that have passed these independent laboratory tests can use the Qi logo and are considered “Qi Certified.”
This presentation discusses the different certification procedures for:
|9:30||The Path to First-Try Success Making a Qi Compliant Wireless Power Receiver Product||David Wilson||Kinetic Technologies, Inc.|
|This session explains in a simple way the basic technology of the wireless receiver, and most importantly, how to design and build a product that will achieve Qi compliance on the first try. The main focus is the most important rules that must be followed, as well as specific problems that commonly happen that result in re-design, failures during Qi compliance testing, or bad experiences for real customers. This is a very practical session, and these lessons come from real product examples that teach us how avoid repeating these unhappy experiences.|
|10:30||Qi Regulatory Type Approval: What You Need to Know||Lam Chi Ho||Intertek|
|Wireless chargers need to meet regulations on use of spectrum, emissions and interference. The presentation will give you an overview of the Qi wireless charging device regulatory type approval requirements of different countries/markets, and illustrate the Qi Specification Version 1.2.4 differences.|
|11:15||Choosing a transmitter reference design|
Comparison of power transmitter reference designs - variations allowed within a Tx design - procedure to approve new Tx designs. Transmitter reference designs and techniques to minimize interference with phones and vehicle electronics.
|13:30||The Path to First-Try Success Making a Qi Compliant Wireless Power Transmitter Product||David Wilson||Kinetic Technologies, Inc.|
This session explains in a simple way the basic technology of the wireless transmitter, and most importantly, how to design and build a product that will achieve Qi compliance on the first try.

|14:15||Load steps and voltage peaks||Se Ho Park||Samsung Electronics|
A rapid change in coupling and a rapid change in load can induce high voltage peaks in receiver circuits.How can wireless chargers prevent damaging receivers? And how do you test this?
|15:00||BREAK - Visit the Exhibition|
|15:15||The Qi specification roadmap||Yongcheol Park||LG|
|Editorial and minor revisions. What is new in version 1.2.4? What new features will be introduced in future revisions of the Qi Specification.|
|15:45||BREAK - Visit the Exhibition|
|16:00||Methods for foreign object detection in inductive wireless charging||Vladimir Muratov||Mediatek|
|Making wireless charging ubiquities along with many other aspects requires addressing safety of technology implementations. Very early in Qi standard development foreign object detection was identified as important technology extension to prevent parasitic metal objects heat up when they accidently or purposely getting coupled into electromagnetic field.
The presentation discusses principals and technical aspects of several methods employed currently by Qi wireless chargers to detect presence of potentially dangerous foreign objects before and during wireless power transfer. Pros and cons of these methods along with intricacies of their implementations are also addressed.
