Canesin, Carlos A. [UNESP]Barbi, Ivo [UNESP]2014-05-272014-05-271997-01-01PESC Record - IEEE Annual Power Electronics Specialists Conference, v. 1, p. 110-114.0275-9306http://hdl.handle.net/11449/132277This paper presents a novel single-phase high power factor PWM boost rectifier, featuring soft commutation of the active switches at zero-current (ZCS). It incorporates the most desirable properties of the conventional PWM and the soft-switching resonant techniques. The input current shaping is achieved with average current mode control, and continuous inductor current mode. This new PWM converter provides ZCS turn-on and turn-off of the active switches, and it is suitable for high power applications employing IGBTs. Principle of operation, theoretical analysis, a design example, and experimental results from a laboratory prototype rated at 1600 W with 400 Vdc output voltage are presented. The measured efficiency and power factor were 96.2% and 0.99 respectively, with an input current THD equal to 3.94%, for an input voltage THD equal to 3.8%, at rated load.110-114engTotal harmonic distortion (THD)Zero current switching (ZCS)Bipolar transistorsElectric commutationElectric current controlElectric distortionElectric inductorsElectric network analysisElectric network topologyElectric power factorElectric switchesPulse width modulationResonant circuitsSwitching circuitsElectric rectifiersTrabalho apresentado em evento10.1109/PESC.1997.616687WOS:A1997BJ13Z00016Acesso aberto2-s2.0-00306551986427185658143370
