The paper suggests a 9-level inverter with quadruple boosting which it considers very useful for small-scale PV systems. The suggested circuit uses capacitors that are a self-balanced voltage without using an additional circuit or complicated control algorithms to balance the voltage of the capacitors. The circuit produces 9 levels with quadruple boost gain at the output terminals by using minimum components as compared with other recent topologies. The circuit analysis and modeling for each output level are described. The switching control strategy uses a simplistic logic control circuit relying on Pulse Width Modulation (PWM) is implemented to ensure balance voltage of capacitors. By the help of MATLAB/SIMULINK, the effectiveness and robustness of architecture are validated. Furthermore, a prototype for this topology is set up and tested in the laboratory using a DSPACE-1104 verifying the theoretical analysis. The experimental setup and hardware implementation are described. The theoretical and experimental results are investigated under various conditions illustrating excellent agreement between the theoretical and experimental endorses the targeted circuit.INDEX TERMS Multi-level boost inverter, switched capacitor, THD and total standing voltage (TSV).

This paper presents a proposed five-level inverter based on conventional five-level Neutral Point Clamped (NPC) topology which is a type of Multilevel Inverters (MLIs). MLI is a great solution for high power application in addition to medium power, low power and renewable energy applications. The proposed topology reduces the number of input DC sources as compared with the conventional five level NPC topology. Also, this circuit reduces the conduction losses by reducing number of switches that turned on in each mode. The circuit operation analysis in each mode is illustrated. A proper modulation strategy based on Pulse Width Modulation PWM is applied on the proposed circuit. The simulation of the proposed circuit is carried out in MATLAB/SIMULINK environment. The results show a comparison between conventional five-level NPC and modified circuits which illustrate a good performance for the proposed one which make it suitable for many applications such as photovoltaic systems.

“…Multilevel inverter (MLI) secara umum bertujuan untuk menghasilkan gelombang output yang mendekati gelombang sinusoidal dengan memanfaatkan tegangan DC dari beberapa level [1], [2], dimana bentuk gelombang output berbentuk seperti gelombang tangga. Semakin banyak jumlah level DC yang digunakan maka bentuk gelombang output dari inverter ini semakin mendekati gelombang sinusoidal serta total harmonik distorsinya akan semakin berkurang (mendekati nol) seiring bertambahnya jumlah level yang digunakan.…”

Fifteen level single phase multilevel inverter is constructed using power circuit consist of 7 MOSFETs, seven independents DC sources, seven diodes, and an H-Bridge circuit. Switching method used in this MLI is sinusoidal pulse width modulation (SPWM) multicarrier where the reference wave in the form of a sinusoidal wave. Multicarrier SPWM circuit is designed using electronic components such as Op-Amp that used as a comparator and some logic gates such as AND, OR and NOT gate to trigger S1, S2, S3, S4, S5, S6, S7, and H-Bridge circuit. Carrier waves used in this MLI modified from the triangle wave that having a frequency into carrier waves without frequency (DC sources) where THD that generated into 5.502%. While methods that use frequency such as Phase Disposition PWM (PD PWM), Phase Shift PWM (PS-PWM), and Carrier Overlapping PWM (CO PWM) that produces THD greater than the proposed method, this system was simulated using PSIM software.
