Motivation

Project Goals

• Build two PCB boards consists power transmitter and power receiver.

• Add a communication channel between the two boards in order to communicate power management calibration.

• Improving the power delivery efficiency based on the HFSS simulation.

Solution AlgorithmThe transistor current and the temperature sensor are the indicators for the M Controller whether to decrease/increase the DC2DC voltage. According to the following logic:

• Temperature goes up, reaching to 70 deg, or the transistor transmits high current.

• M controller decreases the DC2DC voltage Or changes the capacitor

• Temperature goes down, reaching to 60 deg, or the transistor transmits low current.

• M Controller increases the DC2DC voltage Or changes the capacitor
