Stacked-Switched Electrolytic Capacitor-less AC/DC Power Converters
… Vehicles (EVs) has increased the demand for compact, efficient, and reliable On-Board Chargers (OBCs) capable of interfacing directly with the AC grid. Conventional single-phase AC/DC converters often depend on bulky electrolytic capacitors, diode bridges, and hard-switching circuits, leading to …

Miniaturization of Ac-Dc power converters for grid interface
In this thesis we present a two-stage ac/dc grid-connected converter for computer applications. Also known as off-line power supplies, these converters have to meet various demanding specifications such as a wide input voltage range (typically 0-376 V), large voltage step down (typical output …

High frequency power conversion architecture for grid interface
With the present ac-voltage distribution system, ac-dc converters are key components for driving many dc voltage applications from the ac grid voltage. There are a lot of electronic devices that natively operate from the dc voltage including light emitting diodes (LEDs), personal and laptop …

Design and implementation of a universal onboard battery fast charger for transportation electrification applications
… of the EVs. Due to safety limitations and the lack of charging infrastructure, most of EVs are opted with a two-stage on-board charger (OBC) that allows charging of battery packs from standard utility sockets (85-265 V) as per SAE J1772. Existing EVs such as Neighborhood Electric Vehicles …
