From the project
300W SPWM Pure Sine Wave Inverter PCB designed in KiCad 10 using EGS002 controller, IRF3205 MOSFET power stage, transformer interface, cooling fan control and manufacturing-ready outputs.
A 300W SPWM (Sinusoidal Pulse Width Modulation) Pure Sine Wave Inverter PCB designed in KiCad 10.
The PCB implementation was developed based on a reference EGS002 inverter schematic. The project involved PCB floorplanning, component placement, routing, copper pour implementation, ERC/DRC verification, BOM generation, Gerber generation, and manufacturing file preparation.
