US 2016/0105056 A1 · APPARATUS AND METHOD FOR GRID-TO-VEHICLE BATTERY CHARGING

Abstract

A charging system for use in providing power for charging a battery. The system includes a first, alternating-current-to-direct-current, stage and a second, direct-current-to-direct-current, stage. The first stage includes a single-phase diode rectifier for rectifying an input alternating-current input voltage, and a power-factor-correcting sub-circuit including a switch. The second stage includes multiple switches. The system further includes a high-frequency capacitor connected between the first stage and the second stage. The system also includes a controller connected to the switches of the first and second stages and configured to control, by way of the switches, timing of boost inductor current passing through the charging system.
