QI Extended Power Profile Receiver
This solution allows to test the compliance of a contactless power receiver (for example a mobile phone) with the recommendations defined by the WPC (Wireless Power Consortium), for the Extended Power Profile variante
The WPC (Wireless Power Consortium) defines a framework of test procedures, aiming at verifying the global interoperability of power transmitters with power receivers.
Even though Micropross offering covers both receiver and transmitter testing, in both Baseline and Extended Power Profile variantes, this solution here focuses on receiver testing, in the Extended Power Profile mode.
This solution is based on the MP500 TCL3 tester, and the dedicated Wireless Power Consortium accessory kit. Therefore, the Micropross solution has the unique asset of enabling both Wireless Charging, but also NFC testing, based on the same hardware.
Following at 100% the requirements defined in the 'System Description Wireless Power Transfer Volume II: Extended Power Profile 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 Basline Power Profile testing, as well as transmitter testing
The test system is made of the following items :
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 TCL3, and the test platform gives a clear verdict, and displays the reason why a test case passes, or fails.
The coverage of the Baseline Power Profile tests is at 100%, including :
- load modulation amplitude
- frequency demodulation
- selection and ping phase
- certification of power receivers towards the specifications edited by the WPC (Wireless Power Consortium)
- pre-certification at vendor R&D labs of power receivers
