However, in modern industrial applications, most digital controllers are still designed with traditional technologies, such as PID control. Some characteristics of this control technology, such as control time delay and approximate design process, make the results fail to achieve the expected performance. At the same time, this digital control needs to be tested in the process of use, and the process is cumbersome and difficult to achieve. Based on the existing problems, this paper deduces a discrete state space model from the application of the IPOS\u2010PSFB converter, focusing on the characteristics of control delay. At the same time, this paper puts forward a double\u2010loop control strategy to ensure the accuracy of controller design. Among them, the current and voltage loop designs are independent. The current loop and voltage loop adopts two controllers, namely, the proportional controller and PI plus state feedback controller, and the parameters of the voltage loop controller are accurately calculated according to overshoot and bandwidth index. Finally, the IPOS\u2010PSFB converter is simulated and analyzed by MATLAB\/Simulink software, and the controller's steady\u2010state performance and anti\u2010interference are analyzed.<\/jats:p>","DOI":"10.1002\/cta.4406","type":"journal-article","created":{"date-parts":[[2024,12,22]],"date-time":"2024-12-22T18:36:38Z","timestamp":1734892598000},"page":"5288-5304","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Study of a Dual\u2010Loop Digital Control System for High\u2010Power Input\u2010Parallel Output\u2010Series Phase\u2010Shifted Full\u2010Bridge Converters Based on Pole Configuration"],"prefix":"10.1002","volume":"53","author":[{"given":"Zhipeng","family":"Yu","sequence":"first","affiliation":[{"name":"School of Electrical and Electronic Engineering Hubei University of Technology  Wuhan China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-4447-0114","authenticated-orcid":false,"given":"Yang","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering Hubei University of Technology  Wuhan China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,12,22]]},"reference":[{"key":"e_1_2_12_2_1","first-page":"1","volume-title":"2015 Clemson University Power Systems Conference (PSC)","author":"Sadigh A.
