“…Therefore, the inductor and capacitor values should be selected considering this issue, and then minimized fluctuations with parameters adjustment in the ripple relationship [18]. According to Equations (14) and (15), which are calculated for the ZSI structure elements, the ripple relations are a function of inductor and capacitor values, and shoot-through time interval.…”

The high power dissipation is one of the most important problems of the z-source inverter (ZSI). By using an appropriate optimization scheme, the losses can be significantly reduced without any negative impact on the other characteristics of the inverter. In this paper, a multi-objective optimization is implemented in order to reduce the ZSI total losses as well as to improve the z-source active power filter (APF) performance. The optimization is focused on the four important objectives including power losses of the Z-source APF, the initial cost of the system components, the voltage and current ripples, and the boost factor of the z-source network. For these purposes, the multi-objective genetic algorithm (MOGA) is employed. The numerical and simulation results are presented to evaluate the optimization performance. The results show that a good balance can be achieved between the switching power losses, the voltage-current ripple levels, the component costs and the boost factor using the optimized parameters.

In recent years, Z-source inverters (ZSI) have been proposed as a replacement power conversion concept which it has both voltage buck and boost abilities. In addition, ZSI doesn't require dead-time to protection short circuit at two switches any of the same phase leg in the inverter bridge and to achieve optimal harmonic of current, voltage. This paper presents two different control methods (CM) for ZSI. The aim of this study to compare between two modulation methods, there are modified space vector pulse width modulation method (MSVM) and the simple boost control (SBC) about the unique harmonic performance features, the total average and peak switching device power of the inverter system. In addition, this paper also analyzes about the ability exceed modulation index in linear region of two CM using MATLAB/Simulink.

“…However, the main drawbacks of ZSI are high inrush input current, high voltage stress across switches and capacitors and relatively weak boost capability. In addition, the application of ZSI in DC sources is limited due to the discontinuous input current [2]. To overcome these drawbacks, several pulse width modulation (PWM) methods have been proposed to obtain higher boost ability and lower voltage stress on switches, such as maximum boost control [3] and constant maximum boost control [4].…”

A novel quasi-Z-source inverter with Coupled Inductor technique is proposed in this paper. The boost ability of the proposed topology is enhanced compared to classic Zsource/quasi-Z-source topologies. The proposed topology provides a common mode ground with dc source, continuous input current, reduced voltage and current stress on active and passive components. Better energy utilization and suppressed inrush current are achieved by employing coupled inductor cells. Analytical and simulation results are presented to explore the advantages of the proposed design.
