These noise emissions must be avoided since they may be audible and annoying to the final user. This paper analyzes the acoustic noise emissions that appear when a series half-bridge resonant inverter is operated with a phase-accumulator based modulator. This modulation technique has the advantage of operating in the frequency domain, and it is compared with the classical PWM modulator regarding the audible noise generated. The frequencies of the tones in the acoustic noise spectrum are theoretically calculated from the parameters of the phaseaccumulator based modulator. The SFM (Spectral Flatness Measure) is used to quantify the number of cases in which tones are generated by the modulation. Two techniques are applied to the phase-accumulator based modulator and their effect is tested. Theoretical results are experimentally verified. info:eu-repo/grantAgreement/ES/DGA/FSE 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/ 7.503 2018 AUTOMATION & CONTROL SYSTEMS 2 / 62 = 0.032 2018 Q1 T1 INSTRUMENTS & INSTRUMENTATION 1 / 61 = 0.016 2018 Q1 T1 ENGINEERING, ELECTRICAL & ELECTRONIC 14 / 265 = 0.053 2018 Q1 T1 2.4 2018 Computer Science Applications 2018 Q1 Electrical and Electronic Engineering 2018 Q1 Control and Systems Engineering 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-8007-5613 Artigas Maestre, Jose Ignacio Universidad de Zaragoza (orcid)0000-0002-7500-4650 Beltran Blazquez, José Ramon Universidad de Zaragoza (orcid)0000-0001-5832-1163 Dominguez Vicente, Alberto Universidad de Zaragoza (orcid)0000-0003-4633-4551 Barragan Perez, Luis Angel Universidad de Zaragoza 5007 520 Universidad de Zaragoza Dpto.
