Abstract
Various embodiments of a two-stage on-board battery charger that can generate a wide range of output voltages is described herein. Generally, the battery charger employs a first stage buck and boost Power Factor Correction (PFC) converter, and a second stage DC-DC converter. The buck and boost PFC converter is capable of generating variable intermediate DC-link voltages which allow the on-board battery charger to efficiently generate the wider range of output voltages.
