Universidad de Zaragoza (orcid)0000-0003-4886-9461 GaN-based matrix resonant power converter for domestic induction heating 2023 Access copy available to the general public Unrestricted Flexible-surface induction cooktops must operate with a variety of induction heating loads with different behavior and power setpoints to be heated simultaneously. 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. info:eu-repo/grantAgreement/EUR/AEI/CPP2021-008938 info:eu-repo/grantAgreement/ES/AEI/PID2019-103939RB-I00 info:eu-repo/grantAgreement/EUR/AEI/TED2021-129274B-I00 info:eu-repo/grantAgreement/ES/ISCIII/PI21-00440 info:eu-repo/grantAgreement/ES/MECD-DGA-FSE/FPU17-01442 info:eu-repo/grantAgreement/ES/MICINN-AEI/PDC2021-120898-I00 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 6.6 2023 ENGINEERING, ELECTRICAL & ELECTRONIC 39 / 353 = 0.11 2023 Q1 T1 3.644 2023 Electrical and Electronic Engineering 2023 Q1 15.2 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Sarnago, H.
