“…The main disadvantage of multilevel inverter is that, it requires more numbers of power switches which increases the losses and control complexity of inverter [7][8] [9]. Sometimes the output voltage is not limited to DC voltage source similar to traditional cascade multilevel inverter and can be increased with Z network shoot-through state control [10]. Fuzzy logic controller is implemented in DVR to respond quickly on the request from abruptly changing reference signals [11].…”

Inverters are used in many applications now-a-days. One among the major applications is Dynamic Voltage Restorer (DVR), it is a custom power device to guard sensitive loads against voltage disturbances such as voltage sag and voltage swell, both considered to be important parameters of power quality. This paper attempts to study and analyze the performance of a DVR based on a new 11-level symmetrical multilevel inverter, using minimum required numbers of switches with fuzzy logic controller to compensate voltage sag and swell to regulate the load voltage to the best possible extent. The proposed multilevel inverter topology also reduces the cost and complexity in controlling of inverters.

“…A very attractive alternative in multilevel energy conversion is the cascaded topology which uses the series connection of multiple single-phase voltage-source inverters (VSIs) [4] where the output phase voltage waveform of a cascaded inverter with isolated dc voltage sources is achieved by summing the output voltages of bridges. Total harmonic distortion (THD) is used for the evaluation in multilevel inverter.…”

This paper proposes two advanced algorithms for multilevel Z-source inverter (MLZSI), which employ space vector control (SVC) as control algorithm of cascaded H-bridge multilevel Z-source inverter; where output voltage is achieved by summing the output voltages of bridge. In these algorithms different states to generate the same voltage with low THD, as the purpose, are verified and the suitable one is selected. This method is simple and has appropriate performance, where sample time is set quietly. Use of Z-network allows the inverter to generate a wide range of output voltage with high reliability. The accuracy of suggested algorithms is validated with simulation results using MATLAB/SIMULINK software and experimental results based PCI-1716 data acquisition system.

Multilevel Z-source inverters have been proposed as a solution for HV applications. This type of inverters decreases the Total Harmonic Distortion (THD) and has a good performance for different applications such as Flexible AC Transmission Systems, power quality improvement and connecting renewable energy resources to the network. This paper compares several alternative carrier disposition PWM strategies for a five-level Z-source diode-clamped inverter. These strategies are simulated in MATLAB/Simulink. The simulation results illustrate that using Phase Disposition (PD) method, the voltage THD decreases considerably. Also, Alternative Phase Opposition Disposition (APOD) method increases the voltage magnitude more than PD method. Both methods can be effectively used for connecting renewable energy sources to the power grid.
