Abstract
Systems and methods for bi-directional power flow control using a single battery charger are described. According to one example, a semiconductor device is generally described. The semiconductor device may include a charger configured to supply power from a charging interface to a battery in a forward mode, and supply power from the battery to a load in a reverse mode. The semiconductor device may include a first isolation switch disposed between the charging interface and the charger, a second isolation switch disposed between the charger and the load, and a controller configured to enable the first isolation switch and operate the charger in the forward mode, and enable the second isolation switch and operate the charger in the reverse mode.
