The Power Electronics Conference is celebrating 48 years from its first gathering in Belgrade way back in 1973. This long tradition shows that the power electronics society in Serbia is active and has significant results, valuable worldwide. The first conference was held in the Serbian language as a national one, and 47 papers from all over ex–Yugoslavia had been presented. It introduced the popular title abbreviation Ee (abbreviated from Serbian name Energetska elektronika). The next conferences were held in Belgrade in 1975 with 50 papers, Zagreb in 1978 with 94 papers, Sarajevo in 1981 with 95 papers, Ljubljana in 1984 with 104 papers, Subotica in 1986 with 126 papers, and Belgrade in 1988, with 109 papers.
After a long break, due to unfortunate events in ex-Yugoslavia, Power Electronics revives and continues in 1995 in Novi Sad, with 79 papers. It started as a scientific symposium and with an idea to organize it with an exhibition, so for the venue, the International Fair on Electronics and Informatics had been chosen. The next symposiums were held in Novi Sad – in 1997, with 98 papers, and in 1999, with 82 papers. Significant participation of foreign authors resulted in an upgrade of the symposium into an international one, which in 2001 gathered 107 papers, in 2003 101 papers, in 2005 94 papers, in 2007 101 papers, and 2009 105 papers. From 2011 the symposium is included in the new wider-scope event „Energy Days“ in Master Conference Center of Novi Sad Fair and attracted 102 papers in 2011 and 69 in 2013. The conference changed the venue in 2015 and 71 papers have been presented in the Central Building of the University of Novi Sad. The average number of participants was between 150 and 200 of which a significant portion was students and industry experts.
The 19th International Symposium on Power Electronics Ee 2017 established itself and future symposiums as the top Worlds scientific conferences. It was the first one technically co-sponsored by IEEE Power Electronics Society (PELS) and IEEE Industrial Electronics Society (IES), European Power Electronics (EPE) Association, and the European Centre for Power Electronics (ECPE), as well as by IEEE Serbia and Montenegro Section and IEEE Joint Chapter PELS/IES/IAS of Serbia and Montenegro Section. This strong involvement of IEEE brought changes in the paper review and acceptance process, which were performed according to IEEE standards, so 75 papers and lectures by 248 authors from 29 countries were presented. All presented papers were included in the IEEE Xplore database and cited in Web of Science, Scopus, and Google Scholar. The 20th jubilee symposium continued with IEEE technical sponsorship and gathered in 2019 in Novi Sad 73 papers and lectures, which were written by 235 authors & co-authors from 23 countries.
The 21stInternational Symposium on Power Electronics Ee 2021 is the first to be held in virtual form (online) due to the effects of the Covid-19 pandemic. Still, 247 authors from 27 countries (Algiers, Australia, Austria, Bulgaria, Canada, Chile, China, Croatia, Denmark, France, Germany, India, Italy, Montenegro, Nederland, North Macedonia, Paraguay, Poland, Romania, Russia, Serbia, Slovakia, Spain, Switzerland, Turkey, United Kingdom, and the USA) prepared in total 81 papers and lectures (3 invited and 58 top-quality regular papers, 7 Key-notes, 3 invited lectures, 3 industry presentations, 2 tutorials, and 5 papers at national conference). All papers have passed through a double-blind reviewing process by the International Program Committee and technical adjustment by the Secretariat. From 87 submitted, 71 (81%) have been accepted and will be presented in Key-Note, Invited, and Regular sessions. Additionally, two industrial sessions, three distinguished professor lectures, and two tutorials will be organized. I would like to acknowledge the great work of Prof. Petar Grbović, the Technical Chair, who gathered a large team of power electronics experts as topic chairs and reviewers, invited famous key-note speakers and high expert presenters and organized the tutorials, which resulted in high quality of the symposium program. Also, the Publication Chair Prof. Miroslav Vasić managed to go through a complex procedure of preparing fundamentals for post-conference inclusion of all presented papers in the IEEE Xplore digital library and Web of Science, Scopus, and Google Scholar citation bases. His work is highly appreciated.
The presented contributions show the latest research results and new trends, as well as achievements of the industry. It is to the Symposium to evaluate the significance of these contributions. The authors themselves are responsible for the accuracy of the results, statements, and conclusions.
As parallel events, the XXI National conference “Energetska elektronika” (in the Serbian language) and the annual assembly of the Serbian Power Electronics Society will be held.

Konferencija Energetska elektronika obeležava 48 godinu od svog prvog susreta u Beogradu davne 1973. godine. Ova duga tradicija pokazuje da su istraživači iz oblasti energetske elektronika u Srbiji aktivni i da imaju značajne, svetski priznate rezultate.
Prvo nacionalno savetovanje iz Energetske elektronike, popularno Ee, održano je u Beogradu davne 1973. godine sa 47 prikazanih radova iz svih krajeva eks-Jugoslavije. Naredna savetovanja održana su u Beogradu 1975. godine sa 50 radova, u Zagrebu 1978. godine sa 94 rada, u Sarajevu 1981. godine sa 95 radova, u Ljubljani 1984. godine sa 104 rada, u Subotici 1986. godine sa 126 radova i u Beogradu 1988. godine sa 109 radova. Posle duge pauze, zbog nemilih događaja na prostoru bivše SFRJ, Energetska elektronika oživljava i nastavlja svoj rad u Novom Sadu 1995. godine sa 79 radova, ali sada u formatu naučnog simpozijuma i u novom okruženju - Međunarodnom sajmu elektronike i informatike. Sledeći simpozijumi su održani u Novom Sadu – 1997. godine, sa 98 radova i 1999. godine sa 82 rada. Značajno učešće stranih autora rezultiralo je podizanjem nivoa simpozijuma na međunarodni nivo i rad na engleskom jeziku. 2001. godine predstavljeno je 107 radova, 2003. godine 101 rad, u 2005. godini 94 radova, 101 rad u 2007. godini, odnosno 105 radova u 2009. godini. Od 2011. godine simpozijum se održava u sklopu „Dana energetike“ u Master centru Novosadskog sajma, kada je prezentovano 102 rada u 2011. godini i 69 radova u 2013. godini. 18-ti simpozijum održan je na novoj lokaciji, u Centralnoj zgradi Univerziteta u Novom Sadu, kada je prezentovano ukupno 75 radova. 19-ti simpozijum je predstavio radove 246 autora i koautora i okupio učesnike, koji dolaze iz 29 zemalja. U sklopu XX jubilarnog simpozijuma predstavljeno je 73 radova od strane 235 autora/ko-autora iz 23 zemlje sveta.
Vreme održavanja XXI simpozijuma/savetovanja karakteriše pandemija Covid-19 virusa i to je razlog što će on biti po prvi put održan u virtuelnoj formi (online) sa izlaganjima na daljinu. Učesnici, njih 247, dolaze iz 27 zemalja sveta (Alžira, Australije, Austrije, Bugarske, Crne Gore, Čilea, Danske, Francuske, Holandije, Hrvatske, Indije, Italije, Kanade, Kine, Nemačke, Rumunije, Rusije, Paragvaja, Poljske, SAD, Severne Makedonije, Slovačke, Srbije, Španije, Švajcerske, Turske i Velike Britanije), a predstaviće 81 rad i prezentacija (uključujući i one na nacionalnom savetovanju). Svi radovi su prošli kroz proces recenziranja od strane Međunarodnog programskog odbora i tehničkog prilagođavanja od strane Sekretarijata. Želeo bih da istaknem veliki trud prof. dr Petra Grbovića kao predsedavajućeg Programskog odbora, koji je okupio veliki tim stručnjaka energetske elektronike kao i rukovodioca tema i recenzenata, pozvao poznate ključne govornike i visoke stručne izlagače i organizovao tutorijale, što je doprinelo visokom kvalitetu programa simpozijuma. Takođe, želeo bih da se zahvalim i na velikom radu prof. Miroslavu Vasiću, koji je uspeo da savlada kompleksne procedura i omogući da se radovi, nakon izlaganja na simpozijumu uključe u IEEE Xplore bazu podataka i citiraju preko Web of Science, Scopus and Google Scholar-a.
Rezultati ovih radova pokazuju da autori prate najsavremenije trendove u energetskoj elektronici. Na učesnicima simpozijuma je da procene značaj ovih doprinosa, a sami autori su odgovorni za tačnost rezultata, izjava i zaključaka iznetih u svojim radovima.
XXI Savetovanje Energetska elektronika (na srpskom jeziku), koje se održava kao paralelnih događaji u sklopu međunarodnog simpozijuma, predstaviće 5 domaćih radova. Pored toga održaće se i redovna godišnja skupština Društva za Energetsku elektroniku Srbije.
