QI EXTENDED POWER PROFILE TRANSMITTER

Use Cases


This solution will typically be used in the following contexts :
  • certification of power transmitters towards the specifications edited by the WPC (Wireless Power Consortium)
  • pre-certification at vendor R&D labs of power transmitters
Following the recommendations defined by the WPC (Wireless Power Consortium), this solution allows to test the compliance of a contactless power transmitter (for example wireless chargers), for the Extended Power Profile (EPP) Test. The WPC (Wireless Power Consortium) defines a framework of test procedures. It aims at verifying the global interoperability of power transmitters with power receivers. Even though our offering covers both receiver and transmitter testing, in both BPP and EPP variantes, this solution here focuses on transmitter testing, in the EPP mode. This solution is based on the MP500 TCL3 tester, and it's dedicated WPC accessory kit. Therefore, the  solution has the unique asset of enabling both Wireless Charging, but also NFC testing. Those tests are based on the same hardware. Following at 100% the requirements defined in the 'System Description Wireless Power Transfer Volume I: BPP Part 3: Compliance Testing', the main characteristics of this solution are :
  • one compact test tool, embedding all necessary generation and measurement features
  • availability of all normative accessories (TPR, TPT, Foreign objects, Thermo couple, …)
  • fully automated operation mode, for less mistakes in the measurement
  • automated generation of test reports
  • easy migration to EPP testing, as well as receiver testing

Technical data

WPC test set :
The MPManager test platform takes control of the MP500 TCL3, and performs test sessions according to the requirements of the WPC. Physical measurement are done automatically by the MP500, and the test platform gives a clear verdict, and displays the reason why a test case passes, or fails.
The coverage of the EPP tests includes:
  • load modulation amplitude
  • frequency modulation
  • selection phase
  • digital ping
  • The Samsung specific test cases
  • Authentification
