| tx5gm_v1 | System for AC/DC Conversion with Boost Converter and Power Factor Correction Control | Power systems for AC/DC conversion are widely used in industry to convert AC power from the grid into DC power for various loads. This paper presents a system that includes a double-wave half-wave rectifier, a boost converter, and two control strategies: one operating in an open-loop configuration and the other in a closed-loop configuration. These control strategies determine the optimal duty cycle required to maintain a constant output voltage despite variations in input voltage. A second version of the system incorporates current control to achieve power factor correction (PFC). Power quality standards impose strict limits on harmonic distortion to reduce pollution in the electrical network. In particular, the EN 61000-3-2 standard applies to a wide range of loads, including AC/DC conversion systems, and sets limits up to the 39th harmonic. To mitigate harmonic pollution in the network, both passive and active circuits can be employed. Circuits that rely solely on passive elements, such as LC filters, are more cost-effective to implement but fail to meet the standard under all load conditions. The alternative approach employs active circuits, which use electronic components to control and shape the input current to align with the line voltage. This ensures that the input current remains sinusoidal and in phase with the line voltage. Thanks to their high efficiency, these AC/DC conversion systems are utilized in a variety of applications, including LED power supplies, hybrid vehicle charging systems, energy storage from the grid, and compensation for harmonic currents and reactive power. | 2025-05-01T20:36:24.442133 | 2025-05-01T20:39:01.732700 | 2025-05-01T20:38:35.119920 | thesiscommons | 1 | pending | 1 | 1 | https://doi.org/10.31237/osf.io/tx5gm_v1 | CC-By Attribution 4.0 International | [] | Antonino Pagano | [{"id": "2ur45", "name": "Antonino Pagano", "index": 0, "orcid": "0000-0002-0342-4760", "bibliographic": true}] | Antonino Pagano | Engineering; Electrical and Computer Engineering | [{"id": "59bac90254be8103137da292", "text": "Engineering"}, {"id": "59bac90f54be8103137da49d", "text": "Electrical and Computer Engineering"}] | https://osf.io/download/6813db7410d95909b1568ba3 | 0 | not_applicable | not_applicable | [] | 2025-05-02T00:11:55.739077 |
