Qi Developer Conference

Cancelled

This event was cancelled

Intended audience

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. 

Morning Session

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:
  • Standard power transmitters and receivers.
  • Mobile phone accessories
  • Automotive transmitters for inline assembly
  • Subsystems and products that contain an embedded subsystem
  • Substantially similar products (variants of previously certified products)
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.
10:15 BREAK    
       
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.

 

Lunch 12:00 - 13:30 - Visit the exhibition

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.
16:45 END of seminar - Exhibition open until 17:30
