A High Step-Down Isolated Three-Phase ACDC Converter - 2017


During this paper, a single-stage three-part isolated ac-dc converter topology utilizing SiC MOSFETs is proposed for power rectification with a stepped-down output voltage. Unlike the conventional two-stage [front-finish power factor correction (PFC) stage and isolated dc-dc stage] ac-dc converters, the full/[*fr1] bridge structure in dc-dc stage is eliminated during this structure. The high-frequency pulsating voltage is obtained directly from the PFC stage and is applied across the high-frequency transformer, resulting in a a lot of compact design. In addition, there's a bonus of zero voltage switching (ZVS) in four PFC MOSFETs connected to the high-frequency tank, which is not achievable within the case of a standard 2-staged ac-dc converter. A sine-pulse width modulation (PWM)-primarily based management theme is applied with the common-mode duty ratio injection methodology to attenuate the present harmonics without affecting the facility issue. An LC filter is used after the PFC semistage to suppress the line-frequency voltage ripple. Furthermore, the intermediate dc-link capacitor price can be greatly reduced through no extra ripple constraints. Experimental and simulation results are included for a laboratory prototype, that converts 115-V, four hundred-Hz three-part input voltage to twenty-eight-V dc output voltage. The experimental results demonstrate an influence issue of zero.993 with a conversion potency of 95.fourp.c, and total harmonic distortion (THD) as low as three.fivep.c at load condition.
