Abstract	This paper presents a design and simulation-based validation of an Internet of Things (IoT)-enabled, remotelyoperated Variable Frequency Drive (VFD) engineered to convert single-phase alternating current (AC) inputinto a three-phase AC output for precision agriculture applications. The system employs a full-bridge rectifier, aDC link capacitor, and an Insulated Gate Bipolar Transistor (IGBT)-based inverter topology. An ESP32 microcontroller facilitates pulse-width modulation (PWM) generation and remote-control capabilities via Wi-Fi,enabling precise speed regulation of a 1HP, 230V, three-phase induction motor. The simulation utilizes theIR2112 behavioural model and 15A/600V IGBT parameters in Proteus and MATLAB environments. Dead-timeverification of 2-3 microseconds was conducted in Proteus to prevent shoot-through faults. The proposed VFDsystem addresses the practical constraints of rural electrification by allowing three-phase pump operation fromSingle-phase sources, thereby enhancing water conservation through optimized pumping efficiency. Thisdocument outlines the systemarchitecture, mathematical modelling, design calculations, and comprehensivesimulation results, validating the feasibility of the ESP32-based V/f control strategy for single-to-three phaseconversion before physical prototyping.
