Abstract
A wireless direct contact charger includes (a) a voltage supply; (b) a first plate electrode and a second plate electrode; (c) a polarity detection circuit that detects; and (d) a switching circuit. When the first electrode or the second electrode of the portable device is placed on the first plate electrode or the second plate electrode, the polarity detection circuit detects the polarity of the portable device charging terminals (i.e, whether the first electrode of the portable device is in contact with the first plate electrode, the second electrode of the portable device is in contact with the first plate electrode or any other suitable orientations). Based on the detected polarity, the switching circuit connects the first plate electrode and the second plate electrode to the voltage supply to provide an output voltage to the portable device for charging its battery.
