In this context, multi-output inverter topologies aim at achieving independent power management while featuring low power-device count and high power density. However, they suffer from limitations when applying classical modulation strategies to ensure soft switching, which is required to reduce transistor losses and achieve efficient operation. In this scenario, wide band-gap devices reduce switching losses, opening a new paradigm in power conversion where soft switching is not mandatory in order to achieve high efficiency. This paper proposes an implementation of a multi-output resonant inverter based on GaN HEMTs and evaluates various modulation strategies in terms of efficiency under different switching modes. The proposed approach is designed and experimentally validated by means of a 2-coil 2000 W prototype implementation. 000128143 536__ $$9info:eu-repo/grantAgreement/EUR/AEI/CPP2021-008938$$9info:eu-repo/grantAgreement/ES/AEI/PID2019-103939RB-I00$$9info:eu-repo/grantAgreement/EUR/AEI/TED2021-129274B-I00$$9info:eu-repo/grantAgreement/ES/ISCIII/PI21-00440$$9info:eu-repo/grantAgreement/ES/MECD-DGA-FSE/FPU17-01442$$9info:eu-repo/grantAgreement/ES/MICINN-AEI/PDC2021-120898-I00 000128143 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000128143 590__ $$a6.6$$b2023 000128143 592__ $$a3.644$$b2023 000128143 591__ $$aENGINEERING, ELECTRICAL & ELECTRONIC$$b39 / 353 = 0.11$$c2023$$dQ1$$eT1 000128143 593__ $$aElectrical and Electronic Engineering$$c2023$$dQ1 000128143 594__ $$a15.2$$b2023 000128143 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000128143 700__ $$0(orcid)0000-0001-8399-4650$$aSarnago, H.$$uUniversidad de Zaragoza 000128143 700__ $$0(orcid)0000-0002-1284-9007$$aLucía, O.$$uUniversidad de Zaragoza 000128143 700__ $$0(orcid)0000-0002-9655-5531$$aBurdio, J.
