SPWM FED H-BRIDGE VSI

SINGLE PHASE 2-LEVEL SPWM INVERTER WITH VARIABLE VOLTAGE AND FREQUENCY

A single phase two level inverter in H-bridge topology with sinusoidal pulse width modulation technique to generate variable voltage and variable frequency at the output. A L-C filter is used to filtered out the high frequency switching components, so we get an sinusoidal output voltage. The FFT of the output voltage and current waveform are also analysed.
