Abstract

This project involved the design and implementation of a pure sine wave DC to AC power inverter. Through the use of a rectifier topology, we obtained a DC signal of 170V from an AC input of 120Vrms. A high voltage DC signal was then modulated by a control system where the fast switching frequency of the signal-modulation topology was monitored. After modulation, the signal was passed through a low-pass filter to obtain a pure sine wave (AC signal). Issues addressed in the design include spectral quality of the sinusoidal waveform, efficiency, and system-level and PCB design issues.
