Synthesis of Low Cost Inverter Using Harmonic Reduction through Pulse Pattern

This paper focuses on developing a low cost and a low harmonic traditional three level inverter (H-Bridge) using pulse pattern. Multilevel inverter as compared to traditional three level inverters have advantages like low harmonic contents and low electromagnetic interference (EMI) outputs and can operate on several voltage levels. The drawbacks includes: The requirement of isolated power supplies for each stage of the multi converter, cost feasibility and complexity of control system. So there is a need to design such three level inverter using harmonics cancellation which is easy to build, low cost and contain low Harmonics at high ac loads. This paper aims at how we synthesis low harmonic and low cost inverter using three level inverter. The proposed pulse pattern significantly reduces the number of dc voltage sources, switches, and power diodes. The performance of three level inverters with proposed waveform will be simulated in MATLAB.
