Two-Leg Neutral-Point Diode-Clamped Active Front-End Rectifier

open access: yesIEEE Journal of Emerging and Selected Topics in Power Electronics
Active front-end boost rectifiers can replace the uncontrolled diode bridge rectifiers for ac-dc conversion offering high power quality with near unity power factor. The four-switch, B4, topology is gaining interest, either as an inverter or a rectifier, where each switch should withstand the full dc link voltage.
