This paper presents the analysis study between multilevel inverters that are often classified into multilevel voltage source and multilevel current source inverters.  For multilevel voltage source inverter (MVSI), the specific topology studied for this work is the Cascaded H-Bridge MVSI.  Whereas, the multilevel current source inverter (MCSI) is based on Paralleled Inductor Configuration MCSI.  For this study, the analysis between these converters are done with respect to the number of components, the advantages and disadvantages of each converters during performing inverter operation. In term of output voltage and current quality, the percentage of the Total Harmonic Distortion (THD) are measured and compared for both topologies.  MATLAB/Simulink software has been used in this research to design and simulate in order to study the performances of both inverters.

This paper presents a high performance, low cost inverter for photovoltaic systems based on Impedance-source concept. Traditional Voltage-source inverter and Current-source inverter has improved to the new Z-source inverter, with a unique X-shaped network in it. This Impedance-source inverter can provide a single stage power conversion concept where as the traditional inverter requires two stage power conversion for renewable energy applications. A new low cost solar cell powered Z-source inverter system is simulated and the results are compared with the traditional Voltage-source inverter system. Performance analysis, simulation and comparison have been confirmed that the Z-source inverter system is more appropriate for photovoltaic application than their counterparts. Hardware implementation is done to validate the proposed system.

In this paper, latest technology is introduced in substitution to conventional voltage and current type inverter with Transformer based impedance (Z) source inverter in voltage sag assessment and mitigation and compared with voltage source inverter based dynamic voltage restorer. Transformer based impedance source inverters (Trans-Z source inverters) are newly proposed inverters that can be used to overcome downside of voltage source inverter, current source inverter and impedance source (Z-source) inverter. T-Z source inverter consists of transformer with high frequency and low leakage inductance along with low reactive component compared with conventional Z source inverter. In case of T-Z source inverter, voltage stress throughout Z-source capacitor is reduced along with inrush current limitation at startup. This paper presents modeling of T-Z source inverter based dynamic voltage restorer using MATLAB/SIMULINK software along with its THD analysis which is compared with VSI based dynamic voltage restorer. Here abc to dq0 control algorithm is employed. The control technique which is employed for simulation shows excellent results for voltage sag and swell compensation.

Inverter Topology

A generalized three-phase multilevel current-source inverter (MCSI) topology is proposed by implanting the generalized N-level current cells into a three-phase MCSI topology which is derived from the three-phase multilevel voltage-source inverter (MVSI) topology through dual conversion. In the generalized three-phase MCSI topology, each intermediate dc-link current level can be automatically balanced without adding any external circuits, thus a true multilevel structure is provided. Output current of each phase is independently modulated because of being supplied with two DC current-sources. This allows the wealth of existing knowledge relating to the operations, modulations and control strategies of multilevel VSI to be immediately applied to such multilevel CSI. Simulation results of 5-level and 7-level CSI systems are presented to verify the proposed three-phase MCSI topology.

Set Up

It is necessary that the grid-connected inverter was set up in wind power, in order to convey energy generated in wind power to the grid. There are many sorts of inverters, but only two sorts of inverters suit wind power system, which are current-source inverter and voltage-source inverter, and only the later is being widely used. Their configuration, principle, control and characteristic were analyzed in this paper. Results have shown that, voltage-source grid-connected inverter has been the core of the commutation control configuration of direct-driven wind power, which is decided by the peculiarity of itself.
