“…Output voltage ripple can be reduced by choosing a large capacitor. The voltage ripple across each capacitor can be calculated by considering the decrease in voltage across the capacitor when the transistor is closed because the current is negative [47]. The output of this full-wave rectifier circuit will be a DC voltage after the capacitor is installed as a filter, which can be formulated as (2):…”

The demand for increased voltage in renewable energy sources is relatively high. This study examines the rapid development of technology considering the use of voltage-increasing transformers. Voltage regulator circuits are generally used to stabilize the output voltage of the rectifier according to the amount of input from the transformer. However, components for high-voltage stabilizer circuits are rare, which becomes an obstacle to the stabilization of the rectifier output. This study aimed to determine the performance of the designed rectifier circuit against a non-center tap step-up direct current (DC) 400 V transformer and compare the measurement results to manual calculations. The research method is a direct comparison between the input and output voltage values of the transformer after going through a rectifier circuit. This experiment was conducted using the repeatability method three to five times for each voltage variation on the transformer. The voltage variations successfully created are 0 to 50, 0 to 100, 0 to 200, and 0 to 400 V. The output test results from the DC transformer and rectifier circuit show linear results and an increase in peak-to-peak voltage data between the transformer and rectifier outputs by 3.8%.

“…The multistage-stacked boost architecture (MSBA) converter is a recently proposed converter, a large voltage-gain boost converter with neither isolation nor magnetic coupling. It was introduced to the literature in [7,8], and its control and PWM scheme have been studied in [3,9]. One of its advantages is a large voltage gain, and that half of its semiconductors are rated to a low voltage compared to the output voltage.…”

“…A recent contribution to the use of the multistage-stacked boost architecture (MSBA) converter was proposed in [3]. It consists of a PWM scheme that reduces the output voltage ripple without changing the capacitance in capacitors [3]. The strategy consists of taking advantage of the symmetry of the signal.…”

“…In the PWM scheme proposed in [3], the relation among capacitors has an influence on the output voltage ripple for a certain amount of stored energy, which means a wise decision may lead to a smaller output voltage ripple with the same volume of capacitors; the possible combinations of capacitances is very large. This article explores the numerical optimization of the selection of capacitors for the MSBA converter.…”

DC–DC power electronics converters are widely used in many applications, such as renewable energy systems. The multistage-stacked boost architecture (MSBA) converter is a large voltage gain converter whose PWM scheme may reduce a percentage of the output voltage ripple, taking advantage of the symmetry of the voltage signals in capacitors (they are triangular waveforms) to have a symmetry cancelation. The switching ripple is unavoidable; the correct selection of components can reduce it, but this may result in a large amount of stored energy (larger size). The selection of capacitors influences the output voltage ripple magnitude. This article proposes a design methodology that combines a recently introduced PWM scheme with a numerical optimization method to choose the capacitors for the MSBA converter. The objective is to minimize the output voltage ripple by choosing two capacitors simultaneously while ensuring the constraint of a certain (maximum) amount of stored energy in capacitors is not overpassed. The internal optimization was performed with the differential evolution algorithm. The results demonstrate that the proposed method that includes numerical optimization allows having a very low output voltage ripple with the same stored energy in capacitors compared to the traditional converter. In a design exercise, up to 60% reduction was observed in the output voltage ripple with the same stored energy in capacitors.
