Magnetic scanning systems consisting of a magnet and power supply form an integral part of proton therapy and allow the beam position (x, y) to be controlled during spot scanning. Ensuring that the dose is rapidly and precisely distributed within the contour of the tumor requires a high-precision, fast-ramp-speed, and high-stability power supply with accurate control. The present work uses a three-phase bridge rectifier and multiple series-parallel H-bridge converters to propose a prototype power supply for the scanning magnet of a magnetic scanning system. The power supply is controlled using a proportional integral controller using digital signal processing. A prototype of the scanning power supply is developed and tested, and the results demonstrate an output current of \u00b1500\u00a0A, a ramp speed of \u00b140 kA\/s, and a short- and long-term stability of less than 20 ppm.<\/jats:p>","DOI":"10.1063\/5.0053863","type":"journal-article","created":{"date-parts":[[2022,1,3]],"date-time":"2022-01-03T15:53:22Z","timestamp":1641225202000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Power supply for fast-scanning magnet in proton therapy: Design and test"],"prefix":"10.1063","volume":"93","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1205-8405","authenticated-orcid":false,"given":"Jushigang","family":"Yuan","sequence":"first","affiliation":[{"name":"State Key Laboratory of Advanced Electromagnetic Engineering and Technology, Huazhong University of Science and Technology , Wuhan 430074, Hubei, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shiqiang","family":"Pang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Advanced Electromagnetic Engineering and Technology, Huazhong University of Science and Technology , Wuhan 430074, Hubei, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taiyan","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Advanced Electromagnetic Engineering and Technology, Huazhong University of Science and Technology , Wuhan 430074, Hubei, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zijian","family":"Zhou","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Advanced Electromagnetic Engineering and Technology, Huazhong University of Science and Technology , Wuhan 430074, Hubei, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiabao","family":"Zou","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Advanced Electromagnetic Engineering and Technology, Huazhong University of Science and Technology , Wuhan 430074, Hubei, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3223-0321","authenticated-orcid":false,"given":"Chen","family":"Zuo","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Advanced Electromagnetic Engineering and Technology, Huazhong University of Science and Technology , Wuhan 430074, Hubei, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8959-325X","authenticated-orcid":false,"given":"Jiang","family":"Huang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Advanced Electromagnetic Engineering and Technology, Huazhong University of Science and Technology , Wuhan 430074, Hubei, People\u2019s Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2022,1,3]]},"reference":[{"key":"2023081102190140200_c1","doi-asserted-by":"publisher","first-page":"989","DOI":"10.1016\/j.hoc.2019.08.006","article-title":"Proton therapy","volume":"33","year":"2019","journal-title":"Hematol.\/Oncol.
