Abstract:
1. A charger for recharging a target device when the charger is connected to a power source, the charger comprising: an AC feedback circuit configured to provide AC current; a DC circuit configured to provide DC current when receiving power from the AC circuit; a transformer having a primary coil and a secondary coil, the primary coil being connected to the AC circuit, the secondary coil being connected to the DC circuit and being configured to receive inductive energy from the primary coil when the AC circuit is enabled and the primary coil receives AC power; and a magnetically controlled switch that is connected to the AC circuit, the magnetically controlled switch being configured to enable the AC circuit when the magnetically controlled switch detects more than a threshold limit of magnetic field strength, and the magnetically controlled switch being configured to disable the AC circuit when the magnetically controlled switch detects less than the threshold limit of magnetic field strength, wherein the AC circuit is configured to prevent inductive losses in the transformer between the primary coil and the secondary coil when the AC circuit is disabled, and the AC circuit is configured to enable conversion of AC power to DC power using the primary coil and the secondary coil of the transformer when the AC circuit is enabled.
