From the project

NgSpice Digital Twin of a complete off-grid solar power system: H-Bridge inverter (220V/50Hz, PI control, electro-thermal IGBT modeling) and 4kW MPPT boost converter (UC3843 analog control, KCL summing node, gate drive characterization).

NgSpice simulation and KiCad PCB design of a complete off-grid solar power system. The simulation uses manufacturer SPICE models (not ideal switches) and translates dsPIC30F2010 firmware logic into behavioral equations so the control loops can be validated before building hardware.

Two power conversion stages, developed across 10 versions:

1. H-Bridge Inverter — Single-phase 220V/50Hz pure sine wave output using FGY75T120SWD IGBTs, unipolar SPWM, closed-loop PI voltage regulation, electro-thermal monitoring, and hardware fault protection. 2. 4kW MPPT Boost Converter — DC-DC front-end…
