Quazi Z source inverter has an advantage that it can boost or buck voltage to be given to an inverter. Operation of a QZSI is similar to a Z source inverter (ZSI). A conventional photovoltaic application uses a two-stage topology of boost converter and an inverter. A QZSI can be replaced for a two-stage topology to serve the purpose. A 3 KW single phase QZSI is designed and simulated for a standalone photovoltaic system in this paper. The results for total harmonic distortion (THD) of output voltage and mean time between failure (MTBF) of the overall system is compared with a conventional ZSI and two-stage topology for the same rating. MTBF of the overall system is computed using reliability block diagram method. Reliability curve is also plotted for all the three considered topologies.

“…Therefore, designing ZSI using SBC should consider the shootthrough limits allowed on SBC and choose the appropriate modulation index. Compared to similar experiments on ZSI, in [33] designed a ZSI with conventional PWM for a 6 W power rating that used the identical capacitor (C1 and C2) and inductor (L1 and L2) of 470 uF and 10.1 mH, respectively. Using the same capacitor and 1.5 mH less of the inductor, ZSI with SBC in this study can apply on a rating of 100 W. Furthermore, in terms of the control mechanism, this study only used one microcontroller while [33] added another device that only functioned as a bridge between the main microcontroller and the voltage sensing.…”

In a power plant such as micro-hydropower (MHP), an induction generator (IG) is usually employed to produce electrical power. Therefore, an inverter is needed to deliver it with high efficiency. Z-source inverter (ZSI) has been introduced as a topology with many advantages over conventional inverters. This research aims to investigate the performance of ZSI based simple boost control (SBC) in laboratory-scale MHP systems using a rewinding induction generator. This research has been conducted both from simulations and experiments. Based on the result, the waveform characteristic and value of ZSI are close to the desired design. A shoot-through duty ratio of 17% can reach 60 Vrms output voltage, and this condition has a conversion ratio of about 2.05 times. Also, SBC can significantly reduce the Total Harmonic Distortion (THD). ZSI efficiency has a value of 84.78% at 50% of rating load 100 W and an average value of 80%. Compared to the previous study, the proposed design has more economical with the same component for the higher rating power. Moreover, it has a smoother and entire output waveform of the voltage.

“…There are different types of topologies for the multilevel inverter, such as the diode-clamped multilevel inverter [3], the flying capacitor multilevel inverter [4], the cascaded multilevel inverter [5], and many more. However, it has certain problems that need to be avoided, such as that it could damage other appliances during high power output and that it requires a higher number of components [6].…”

“…Due to the importance of a multilevel inverter for DG configuration, this project is conducted in order to investigate a simple current control strategy by using a current feedback loop using a low-cost microcontroller that can be developed for an undergraduate project. The papers [5,11,12] used MATLAB SIMULINK as code genera-tion between the controller and the microcontroller. All of those papers used a low-cost microcontroller.…”

Nowadays, more research projects have described a converter that is widely used at the distributed generation (DG) level in order to increase the amount of electrical power generation. The converter is known as an inverter when only one DG source is used or as a multi-inverter when several DGs are used. Here, the application of a multilevel inverter with a C2000 microcontroller (Texas Instruments (TI) TMS320F28335 microcontroller), which can be implemented with a current feedback loop, is investigated. This microcontroller acts as a communication interface between MATLAB SIMULINK and the multilevel inverter. Meanwhile, the current control model is modeled in MATLAB for designing the control strategy. It is where the multilevel inverter switches are triggered by using pulse-width modulation (PWM) signals generated by the microcontroller output. At the same time, the proportional integral derivative (PID) current control is used in order to allow the load current to follow the reference current. Based on the results, it can be summarized that the multilevel inverter is a very useful device for the next DG sources when it is combined with current control for load current distribution. From this investigation, it can be seen that in the future DGs could be connected to a multilevel inverter structure, where it will reduce the dependency on filter design and have a more sinusoidal output to the load for different DG power ratings.
