چکیده

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.

An LCL-filtered Single-phase Multilevel Inverter for Grid Integration of PV Systems

Integration of the PV into the electrical grid needs power electronic interface. This power electronic interface should have some key features and should come up with grid codes. One of the important criteria is the quality and harmonic contents of the current being injected to the grid. High-order harmonics of the grid current should be very limited (lower than 0.3% of the fundamental current)...

Grid Integration of a Single-Source Switched-Capacitor Multilevel Inverter with Boosting Capability

This paper investigates the connection of a single-phase multilevel inverter structure to an existing power grid. The applied voltage source inverter is able to generate a near sinusoidal voltage waveform with an amplitude six times the input voltage by using a single DC input power supply. A proportional-resonant (PR) controller regulates the injected current into the grid. While the EPLL is u...

A New Single-phase Symmetrical Cascade Multilevel Inverter with Low Number of Power Switches

In this paper a new 5-level single phase symmetrical cascade multi-level inverter is proposed. The proposed topology contains combination of unidirectional and bidirectional power switches based on output voltage level number. The number of power switches and withstanding voltage of powers witches were reduced related to the other topologies. This configuration can be extended to the n-level in...

Transformer-based Single-source Multilevel Inverter with Reduction in Number of Transformers

Single-source binary hybrid multilevel inverters with cascaded transformers have a bulky transformer connected to their main H-bridge cells in each phase. This bulky transformer has been eliminated in this work without any effect on operation and modulation strategies. The proposed topology has significant advantages from view point of dimensions and number of transformers, design of transforme...
