This change consists in replacing one of the converter capacitors by a structure known as switched capacitor. After performing a mathematical analysis, it has been shown that the converter can offer a greater attenuation to the input voltage with higher duty-cycles when compared to other similar converters. This adaptation does not cause stress of voltage and current over the switch and other semiconductors. The modified SEPIC-Buck converter was evaluated by a computational way and, simulations results validate its equations and operation modes.
