How to add the electronic load to the STEVAL-WLC38RX to simulate wireless charging of a smartphone

[DZaot1]

Hello everyone,

to simulate wireless charging of a smartphone (I want to achieve 5W transmission to the load), I need to use an electronic load and add the load step by step. Since the wireless charging system cannot immediately absorb high current, what sequence of loads should I connect to the STEVAL-WLC38RX to ensure it absorbs 5W?

Hi Domenico

Welcome to community.

You can follow application notes, wlc38 default vout is 5V, you can use e-load and add the load step by step, for example 200mA, when you reach 1A, it means RX absorbs 5V/1A/5W power.
