“…The proposed split-phase diagram helps in increasing the efficiency by reducing the PSC converter's output impedance. This paper complements our work in [14] by using a splitphase control diagram [15] to operate the 8 switches of the PSC-boost. The implemented control diagram increases effectively the PSC-boost efficiency in reducing the output impedance.…”

“…Adding more output multipliers and keeping the main converter part (primary side) is the main aspect of the MBC converter [5][6][7][8][9][10][11][12][13]. The MBC increases the regulated output voltage by adding voltage cells, which are basically switched capacitors cells, but have drawbacks, such as the failure to produce the actual output voltage at higher duty cycles [14]. The proposed model in [14] uses a switched capacitor converter (PSC) as a primary stage on a conventional boost converter.…”

This paper proposes a split-phase control diagram for a new design of a DC-to-DC boost converter which is called PSC-boost and studies its performance. The PSC-boost has two sides, the primary is a PSC converter and the secondary is a DC-to-DC boost converter. The effect of applying the split-phase control diagram helps reduce the output impedance successfully and increases efficiency by 3%. The simulated and analytical results have been proven to validate the effect of the split-phase diagram. The simulated design contains five switches, five capacitors, seven diodes, and three inductors to step up 10V into 160V at 200KHz and 100KHz switching frequencies. The LTspice simulator was used to design and test the proposed model.

Optimization of a Multilevel Inverter Design Used for Photovoltaic Systems under Variable Switching Controllers

Among multilevel inverters (MLIs), two-level inverters are the most common. However, this inverter type cannot maintain total harmonic distortion (THD) due to its limited number of levels. Reductions in THD are inversely proportional to the number of levels where increased output occurs in diverse ways, and the use of fewer components with low harmonic distortion is necessary for such reductions. This work proposes a seven-level (7L) MLI design with a small number of components and low harmonic distortion. The proposed MLI is combined with switched capacitor (SC) cells to promote output levels and at the same time to boost the input voltage. The connections between the capacitor and the source are based on the series to parallel topology, where the charging and discharging of the SC cells are caused by fluctuations in their connection. The output of the SC cell is combined with an H-bridge inverter controlled by a proposed PWM controller. The simulation result of the SC 7L inverter was completed using LTspice software. A comparison of the proposed topology with that of other current MLI led to better validation results. The proposed design shows a reduction in the THD with fewer components. The cost and size of the proposed inverter is minimal due to the smaller number of components. Ohmic load and inductive ohmic load were used as loads for the system.
