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.

|10:00||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:
|10:30||Qi power control principles and consequences on Tx design||Christian Beia, Guillaume Combes, Lionel Cimaz||ST Microelectronics|
|The presentation describes the Qi system level operation to accomplish the power control. On top of the principles to design the power modulation, the presentation shows the behavior of the control loop and demonstrates the criticality of the message demodulation at Tx side. It describes in particular the dependence of the demodulation quality with regard to the system operating point. Finally, the presentation proposes a multi-path demodulation helping to ensure a correct demodulation in all situations.|
|11:30||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.|
|13:30||Coil Specific Considerations – choosing the optimal coil for my application||Joerg Hantschel||Wurth|
|The coils are besides the IC’s the most important components in a wireless power system. To choose the right coil has an impact on the performance and the success of the device in the market. The integration of the coil in a device is depending on various parameters.
This presentation will give you guidance on:
|14:15||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.
|15:15||Regulatory type approval of Qi products||Lam Chi Ho||Intertek|
|Wireless chargers need to meet regulations on use of spectrum, emissions and interference. This presentation covers the regulatory requirements for CE, CCC, FCC and the approvals needed in the US/Canada, Europe and China.|
|16:00||The Path to First-Try Success Making a Qi Compliant Wireless Power Transmitter Product||David Wilson|
|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. 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.
