This paper proposes a reconfigurable induction motor (IM) drive with harmonic cancellation ability for shipboard power grids. Power electronic building blocks (PEBBs) and universal controllers (UCs) are used for reconfigurable (multi-function) control. When there are no significant current harmonics in the power grids, the UC controls the IM only. When significant current harmonics are introduced in the power grid, the UC reconfigures the active front end from an active rectifier to an active filter to cancel the harmonics while continuing to control the IM. Therefore, this reconfigurable drive system is universal in applications for harmonic cancellation requirement as well as controlling the existing IM. It supports power quality considerations without adding more equipment to the power system and therefore reduces the shipboard power system cost.
