The proposed converter comprises an isolated three-phase uncontrolled multipulse rectification stage directly connected to a single-phase inverter stage, without the use of DC to DC intermediary stage, resulting in more simplicity for the overall circuitry, assuring robustness, reliability and reduced costs. Furthermore, the multipulse rectifier stage is capable to provide high power factor and input currents with low total harmonic distortion (THD). The output voltage of the PMG varies from 260V rms (220 Hz) to 380V rms (360 Hz), depending on load conditions. The output single-phase inverter stage was designed to operate with wide range of DC bus voltage, maintaining 120V rms, 60 Hz output. Measured total harmonic distortion for the AC output voltage represents less than 2%, at 3.6kW nominal linear load. © 2010 IEEE.1726-1731engAC to AC converterHigh input power-factor converterPermanent Magnet GeneratorPower qualityAC-AC convertersAc-to-ac converterDC-bus voltagesDesign and DevelopmentHigh input powerHigh power factorInput currentLinear loadsLoad conditionMulti-pulse rectifiersMultipulsesNaval applicationsOutput voltagesReduced costSingle-phase invertersTotal harmonic distortionsAC generator motorsElectric power factor correctionHarmonic distortionHVDC power transmissionMagnetic devicesPermanent magnetsPower electronicsWave filtersElectric rectifiersTrabalho apresentado em evento10.1109/SPEEDAM.2010.5542286Acesso aberto2-s2.0-779565757926427185658143370
