Universidad de Zaragoza (orcid)0000-0003-4886-9461 Series-Resonant Matrix Inverter with Asymmetrical Modulation for Improved Power Factor Correction in Flexible Induction Heating Appliances 2023 Access copy available to the general public Unrestricted Induction heating appliance operation is constrained by the nonlinear pot material behavior under the generated magnetic field. The equivalent load seen by the inverter varies with the intensity of the field, meaning that this variation is dependent on the mains voltage. In flexible-surface induction cooktops, this fact is combined with a high coil number and different pots to be powered simultaneously, increasing the complexity to control the transmitted power while maintaining proper mains current consumption. In this article, two noncomplementary asymmetrical modulations with in-cycle parameter variation are proposed for improved power factor correction while avoiding the need for switching frequency variation and intermodulation noise in multiload systems. The proposed strategies are analyzed and experimentally tested using a 3.6 kW multi-inverter prototype featuring five induction coils. info:eu-repo/grantAgreement/ES/MECD-DGA-FSE/FPU17-01442 info:eu-repo/grantAgreement/ES/MICINN-AEI-FEDER/PID2019-103939RB-I00 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/ 7.5 2023 AUTOMATION & CONTROL SYSTEMS 6 / 84 = 0.071 2023 Q1 T1 INSTRUMENTS & INSTRUMENTATION 2 / 76 = 0.026 2023 Q1 T1 ENGINEERING, ELECTRICAL & ELECTRONIC 25 / 353 = 0.071 2023 Q1 T1 3.395 2023 Electrical and Electronic Engineering 2023 Q1 Control and Systems Engineering 2023 Q1 Computer Science Applications 2023 Q1 16.8 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Sarnago, H.
