IoT high-frequency electronic transformer with dimmable output voltage using PWM signals

This work presents the design, simulation, and implementation of a low-power electronic transformer, which output effective voltage can be controlled wirelessly through WIFI, via user interface on mobile phone. The methodology used in this project consists 4 stages, rectifier, an inverter, inverter’s control system, ferrite reducer. inverter has full-bridge design was implemented using MOSFET. system vary frequency duty cycle signals, by phase shifting thus achieving functionality reducing voltage. Circuit simulations were performed PsPice Orcad. mathematical model built transformer are carried out. designed operates with maximum input 120 Vrms at 60 Hz frequencies between 20 kHz 30 kHz, interface; reduce signal to 10 power 50 W. feasibility developing transformers variable voltage, remotely IoT technology.
