Abstract
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. Higher voltage-rated power semiconductor devices not only imply slower response with lower overall efficiency but also higher cost and size. Thus, multilevel inverters become a viable solution. This paper investigates a two-leg neutral-point diode-clamped B8 rectifier allowing the series connection of fast, efficient, and low voltage rating switches. The proposed rectifier has better performance and efficiency than the B4 rectifier. Only two inductors instead of three are required. Model predictive current control (MPCC) is developed for accurate current tracking. A model of the proposed rectifier is detailed for the implementation of MPCC. The concept is validated by simulation and experimentation.
