Newly-Constructed Single Phase MultilevelInverter for Distributed Energy Resources

 ABSTRACT:

Distributed energy resources systems are small power generation tools used to afford substitute solution or added enrichment of traditional electric power system. This paper is mainly concentrated on 1Ø multi-level inverter for Distributed Energy Resources. The objective of this paper is to reduce switches with increase in multi-level outputs which inherently reduces the cost & harmonics. Seven-level inverter with 6 switches and thirteen-level inverter with 8 switches are carried out using MATLAB 7.10 version (Simulink). Total Harmonic Distortion (THD) is analysed for two types of multilevel inverter in MATLAB. For implementing hardware, the circuit is tested in PROTEUS 7.4 version software which helps in troubleshooting real time problem.

KEYWORDS:

1.      Multi-level inverter

2.      Distributed Energy Resources (DER)

3.      Renewable energy

4.       Solar energy

5.      Wind generator

SOFTWARE: MATLAB/SIMULINK

CONCLUSION:

This paper reports a substantial saving of switching devices used for a 1Ø multi-level inverter topology that harvests an important multi-level output for DERs. The agreement between the simulated software results and the observed output from the hardware circuit shows clearly that the new multi-level topology for DER works as expected generating desired seven level output using only 6 power switches. Total harmonic Distortion and reduction in switching are appreciable.
