PARTS
CIRCUIT DESCRIPTION: SUPPLY SECTION The ckt is fed from a 5v dc supply & that voltage taken from
230v ac line by stepping down the voltage from 230v to 12v.This 12v again converted to DC through a bridge rectifier .
A capacitor is connect across the rectifier for two purpose i.e. filtering and boosting. The 5v dc is obtained by voltage
regulator (7805). INVERTER SECTION: This ckt is consists of four IGBTs, which is triggered by two
pulse generator ,(one for +ve half and one for –ve half) CONTROLLING SECTION: In the controlling section the input pulse commutated for
five times to eliminate the lower order harmonics.
A resistive load is connect to see the output.
description
This project Report deals with the Harmonic analysis of Single Phase inverter with Pulse Width Modulation (PWM).
It includes both simple and practical inverter. The Simulink model for both simple and practical
inverter has been simulated in MATLAB. Its various parameters such as R,C and Filter design.
These parameters are varied and the resulting voltage and current graphs has been studied.
Conclusion
The future work includes improving the stability of the system and also to study various instability in SPWM with harmonic analysis in Three phase and ways to eliminate it and to design an actual household SPWM-VSI with a better controller design.
