Abstract
Embodiments pertain to a wireless power transfer (WPT) system including: a wireless power transfer link (WPTL); and on a load-side of the WPTL, a high frequency (HF) rectifier positioned between the WPTL and a load, wherein the load includes a low frequency (LF) power factor correction rectifier and a current shaping DC/DC converter. The high frequency rectifier may be connected in series to the LF power factor correction rectifier via an HF bypass capacitor. The WPTL may be operated in load independent voltage output (LIVO) mode.
