Regarding the question of wireless charging conversion rate, I hope the experts can help analyze it [Copy link]

I am working on wireless charging. The QI standard wireless charger generally has an input and output of 5V, a power of 5W, and a conversion efficiency of about 70%. My customer now needs a conversion rate of about 85%. Does this conversion rate have something to do with the power of the wireless charger? Or is it related to both the output and the power?

"Conversion rate" refers to the conversion of one substance into another, with some conversion and the rest not converted. "Conversion efficiency" refers to the efficiency of energy conversion.

Wireless charging has three powers: 1. The input power of the wireless charger, which is the power of the electric energy input to the charger coil; 2. The output power of the wireless charger coil, which is the power of the magnetic field generated by the current passing through the coil to transmit energy to the outside. 3. The actual power of the device when charging. Input power > Output power > Actual power

The conversion efficiency can be understood as the efficiency from the transmitter input to the receiver output of the wireless charger.

I understand, thank you

This also depends on your transmission distance.
