Hi Samir Ltaief,

Thanks for posting in the Infineon Developer community!

This debug log is used while debugging the firmware of WLC1115. This log will use the short form for the packets used in the Qi specification. For example, CEP stands for Control Error Packet, ASK stands for Amplitude Shift Keying, FSK stands for Frequency Shift Keying, etc.

Also, this log uses WLC1115-specific pin names as acronyms like VBRG(VBRIDGE), NTC(Negative Temperature Coefficient), VIN_V, PTX stands for Transmitted Power, etc.

Other common short forms used include TEMP(Temperature), calib(Calibrated), Thres(Threshold), etc.

Thanks,
Ajeeth

Hi,

Thanks!
the efficiency = (PRX/PTX )*100, Is it correct?

Hi,

PRx/PTx will give system efficiency excluding buck converters and is also not very accurate.

So, I recommend you to do power measurement at the input(Terminals/VBus) and Output(Load) and calculate efficiency with the obtained values.

Thanks,

Hi,

can you please give me  an example?
If I connect a smartphone as a receiver. How I can calculate the efficiency?

Hi,

In the case of smartphones, Battery is the load. You have to measure voltage and current near the load(Battery in this case) to get the Output Power. Input Power can be measured near the Input terminals.

Thanks,
