In single-phase systems, electrolytic components are commonly used due to their high energy density, which helps mitigate low-frequency ripple caused by power oscillations between the DC and AC sides. However, these components have a limited lifespan, which compromises the system\u2019s long-term reliability. This work proposes and evaluates the Stacked Switched Capacitor (SSC) topology as a power decoupling technique, implemented within a 200 W Cuk converter. The proposed SSC design enables a substantial reduction in required capacitance, replacing a conventional 600 \u03bcF capacitor with only three 36 \u03bcF capacitors, while maintaining voltage stability and output power performance. Simulation results show a high efficiency of 94% and a DC-link energy of 0.992 J, confirming the SSC\u2019s ability to effectively mitigate voltage ripple at twice the grid angular frequency (2\u03c9, rad\/s) without compromising system durability. Comparative analysis with conventional decoupling strategies demonstrates that the SSC topology offers a compact, efficient, and reliable alternative, reducing the number of required passive components and switching devices. These results provide a strong basis for further exploration of SSC-based designs in space- and cost-constrained single-phase DC-AC applications.<\/jats:p>","DOI":"10.3390\/computation13120276","type":"journal-article","created":{"date-parts":[[2025,12,2]],"date-time":"2025-12-02T15:31:17Z","timestamp":1764689477000},"page":"276","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Computational Analysis of Unipolar Stacked Switched Capacitor Architecture for Active Power Decoupling in Single-Phase Systems"],"prefix":"10.3390","volume":"13","author":[{"given":"Omar","family":"Rodr\u00edguez-Ben\u00edtez","sequence":"first","affiliation":[{"name":"Centro Nacional de Investigaci\u00f3n y Desarrollo Tecnol\u00f3gico (CENIDET), Tecnol\u00f3gico Nacional de Mexico, Cuernavaca 62490, Mexico"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4236-6903","authenticated-orcid":false,"given":"Mario","family":"Ponce-Silva","sequence":"additional","affiliation":[{"name":"Centro Nacional de Investigaci\u00f3n y Desarrollo Tecnol\u00f3gico (CENIDET), Tecnol\u00f3gico Nacional de Mexico, Cuernavaca 62490, Mexico"}]},{"given":"Mar\u00eda Del Carmen","family":"Toledo-P\u00e9rez","sequence":"additional","affiliation":[{"name":"Centro Nacional de Investigaci\u00f3n y Desarrollo Tecnol\u00f3gico (CENIDET), Tecnol\u00f3gico Nacional de Mexico, Cuernavaca 62490, Mexico"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9927-2011","authenticated-orcid":false,"given":"Ricardo E.","family":"Lozoya-Ponce","sequence":"additional","affiliation":[{"name":"Divisi\u00f3n de Estudios de Posgrado e Investigaci\u00f3n, Tecnol\u00f3gico Nacional de M\u00e9xico-I.T. de Chihuahua, Av.
