Abstract:
An apparatus for wireless power transfer is disclosed. An alternate apparatus and a system perform the functions of the apparatus. The apparatus includes a wireless power transfer (“WPT”) pad, a secondary circuit with a rectification section that receives power from the WPT pad, a capacitor, and a first rectification device connected to the capacitor. The capacitor and first rectification device are connected in parallel with the rectification section and in parallel with a load. The apparatus includes a second rectification device connected to the rectification section and an intermediate node between the capacitor and first rectification device.
