Input circuit for a wireless power receiver, wireless power receiver, and method for operating the wireless power receiver

Abstract

The invention relates to an input circuit (9) for a wireless power receiver (10), the input circuit (9) comprises: an active rectifier (5) configured with output nodes; a voltage regulator (7) connected to the output nodes, wherein the active rectifier (5) is configurated to output a DC voltage (VDC) at the output nodes, wherein the voltage regulator (7) is arranged to actively affect the said DC voltage (VDC); a control structure adapted to control the DC voltage (VDC), wherein the control structure comprises a first control loop operatively coupled to the voltage regulator (7) and configured to control a voltage regulation operation of the voltage regulator (7), and a second control loop operatively coupled to the active rectifier (5) and configured to control a rectifier operation of the active rectifier (5), operates with a faster response time (more than two order of magnitude faster) than the second control loop, and wherein the first control loop is operably engaged with the second control loop. The invention also relates to a wireless power receiver (10) and a method for operating the wireless power receiver (10).
