This study presents a real-time temperature monitoring and control system for a Class E inverter in a low-power wireless power transfer prototype. The system was designed to monitor voltage, current, temperature and output power while supporting zero-voltage switching and protecting the inverter from overheating. MATLAB Simulink was used to model the transmitter and receiver stages, while Proteus supported PWM generation, control logic, and PCB design. The hardware prototype integrated a microcontroller, MOSFET driver, MOSFET, resonant coil network, rectifier, temperature sensor, LCD display, relay-controlled cooling fan and ESP32-based IoT monitoring. Simulation and hardware testing confirmed high-frequency power transfer, rectified DC output, and automatic fan activation at the 37 °C threshold. The findings show that active thermal control improves the safety, stability, and practicality of low-power wireless power transfer systems.
