Abstract: An apparatus for inductive power transfer (“IPT”) includes an active bridge section with input terminals that receive power from a constant current source, where the active bridge section operates at a fixed switching frequency, a primary resonant capacitor connected in series with an output terminal of the active bridge section, and a primary IPT coil connected in series with the primary resonant capacitor, where power is transferred wirelessly between the primary IPT coil and a secondary IPT coil, and the secondary IPT coil is connected in series with a secondary resonant capacitor, which is connected in series with an output rectifier section that receives power from the secondary IPT coil and comprising output terminals for connection to a load. The apparatus includes a controller that regulates output voltage to the load, where the controller regulates output voltage to the load by controlling switching of the active bridge section.
