On-Board Charger (OBC) Single-Stage Converter

An on-board charger for charging a battery, such as a traction battery of an electric vehicle, includes an AC/DC converter and a pulsating buffer (PB) converter. The AC/DC converter is configured to convert an AC input from a mains supply into an output having a DC voltage and a current ripple. The PB converter is connected to the AC/DC converter and is configured to process the output of the AC/DC converter to reduce or minimize the current ripple thereof and transform the output of the AC/DC converter into a battery-level DC output for charging the battery.
