Universidad de Zaragoza (orcid)0000-0001-7530-2343 A front-end PFC stage for improved performance of flexible induction heating appliances 2020 Access copy available to the general public Unrestricted Flexible cooking surfaces, eg. fully active surfaces, have gained lately an increasing importance in the domestic induction heating. Multi-inverter structures are a cost-efficient solution to develop this technology. However, they add control restrictions that can be solved with a power factor corrector (PFC) stage as proposed in this work. The proposed converter and modulation strategy work with zero voltage switching (ZVS), decreasing the switching losses, enabling a higher working frequency and, therefore, decreasing the magnetic devices size. The bus voltage is controllable and can be increased, easing the load power control and decreasing current through load and inverter and, so, the power losses. Besides, the switching frequency is constant in the mains cycle and can be modified to synchronize the load inverter and the PFC stage avoiding intermodulation noise. A 3.6 kW prototype has been implemented fulfilling the EMC requirements. The experimental waveforms and efficiency have been measured to prove the feasibility of this proposal. info:eu-repo/grantAgreement/ES/DGA/FSE info:eu-repo/grantAgreement/ES/MEC/FPU15-01590 info:eu-repo/grantAgreement/ES/MINECO/RTC-2017-5965-6 info:eu-repo/grantAgreement/ES/MINECO/TEC2016-78358-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.706 2020 ENGINEERING, ELECTRICAL & ELECTRONIC 256 / 273 = 0.938 2020 Q4 T3 PHYSICS, APPLIED 153 / 160 = 0.956 2020 Q4 T3 MECHANICS 127 / 135 = 0.941 2020 Q4 T3 0.238 2020 Condensed Matter Physics 2020 Q3 Electrical and Electronic Engineering 2020 Q3 Mechanics of Materials 2020 Q3 Mechanical Engineering 2020 Q3 Electronic, Optical and Magnetic Materials 2020 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Sarnago, H.
