Universidad de Zaragoza (orcid)0000-0003-4886-9461 Mains-Synchronized Pulse Density Modulation Strategy Applied to a ZVS Resonant Matrix Inverter 2021 Access copy available to the general public Unrestricted Multi-output inverters have become a key enabling technology to increase surface flexibility in domestic induction heating appliances. The most commonly used power converter topologies are based on electromechanical relays in order to multiplex the connected loads and obtain a proper heat distribution. This solution, which is used in combination with other modulations such as square waveform, relies on the thermal inertia of the pot as it needs long power-averaging periods to reduce the reiteration of the switching noise. However, it presents a significant limitation in terms of acoustic noise, reliability, and thermal performance. To overcome these limitations, complete solid-state inverters that can be operated at higher frequencies are proposed. This change in the design paradigm of the pulse density modulation strategies leads to improved thermal control in the pot and better user experience, but at the same time increases challenges due to design constraints imposed by electromagnetic compatibility regulations. This article analyzes the possibilities of a new mains-synchronized pulse density modulation applied to a flexible induction cooktop that uses a multiple-output ZVS resonant inverter topology. The feasibility of the control strategies has been tested by means of a prototype featuring 12 2-kW induction heating loads. © 1982-2012 IEEE. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 8.162 2021 AUTOMATION & CONTROL SYSTEMS 6 / 65 = 0.092 2021 Q1 T1 INSTRUMENTS & INSTRUMENTATION 3 / 64 = 0.047 2021 Q1 T1 ENGINEERING, ELECTRICAL & ELECTRONIC 28 / 274 = 0.102 2021 Q1 T1 3.519 2021 Control and Systems Engineering 2021 Q1 Computer Science Applications 2021 Q1 17.1 2021 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Sarnago Andía, H.
