概述
描述
The P9412-EVK evaluation kit demonstrates up to 30W wireless power transfer in proprietary receiver mode with the P9247-RB-EVK wireless power transmitter evaluation kit. The P9412-EVK supports up to 15W in EPP mode when paired with a Qi-compatible wireless power transmitter. The P9412-EVK can also be used to evaluate the WattShare™ feature when the P9412-EVK delivers up to 6W to a Qi-compatible power receiver.
The P9412-EVK features P9412, a highly-integrated single-chip wireless power receiver with integrated capacitive divider, Multiple-Time Programmable (MTP) non-volatile memory, and an industry-leading 32-bit Arm® Cortex®-M0 processor. Feature expansion, updating control firmware, and device functions can be easily done on the P9412-EVK.

Wireless power transfer uses an air-core transformer with separate transmitter and receiver coils, making accurate performance modeling difficult due to low magnetic coupling and increased losses. This paper addresses simulation challenges and describes methods to approximate circuit behavior. It demonstrates best practices for tuning Qi and PMA inductive resonance circuits to maximize charging efficiency for mobile devices.
