Abstract

The disclosure is concerned with a receiver module (21) for wireless power transmission. The receiver module (21) comprises at least three transformer circuits (T) for transforming a received power transmission signal (Vin) into a supply signal (Vout) for a connectable energy storage device, such as a battery (23). The transformer circuits (T) are connected in series on a primary side (I). Due to a respective coupling capacitance (Cps1 to Cps4), each of the transformer circuits (T) may be unbalanced with respect to their output signals (V1, V2, V3, V4). To balance the output signals (V1, V2, V3, V4), which are used to provide the supply signal (Vout), at least two bypass devices (B) comprising at least one bypass capacitor (Cpp1, Cpp4) are connected in parallel to the first and last of the transformer circuits (T) in the serial connection.

Abstract

A multiple output rectifier achieving effective supply of power to a plurality of loads. The multiple output rectifier converts an AC input signal into a first rectified output signal and a second rectified output signal, wherein the AC input signal has a fundamental period dividing into a first partial period where an AC current flows in a first direction and a second partial period where the AC current flows in a second direction being a reverse direction to the first direction. The multiple output rectifier includes a first input terminal and a second input terminal different from the first input terminal for input of the AC input signal. The multiple output rectifier further includes a common output terminal, a first output terminal, and a second output terminal. The common output terminal, the first output terminal, and the second output terminal are decoupled from each other for operation in a multiple output operative mode. In the multiple output operative mode and during the first partial period the multiple output rectifier is adapted to maintain polarity of the AC input signal and to transfer it to the second output terminal and the common output terminal as the first rectified output signal. Further, in the multiple output operative mode and during the second partial period the multiple output rectifier is adapted to reverse polarity of the AC input signal and to transfer it to the first output terminal and the common output terminal as the second rectified output signal. The multiple output rectifier may also comprise a switching circuit component between the first output terminal and the second output terminal to change the multiple output operative mode to a full bridge operative mode and vice versa.

A more efficient solution for a detection of operating conditions in an inductive power transfer system and for improved control of the inductive power transfer system. An operating condition at a secondary side of an inductive power transfer system is detected by measuring at least one electric variable at a primary side of the inductive power transfer system which is dynamically coupled to the operating condition at the secondary side of the inductive power transfer system. Then follows an analysis of the at least one electric variable over time at the primary side of the inductive power transfer system. This allows to detect a change of the operating condition at the secondary side of the inductive power transfer system. Also provided is a control method and related controller apparatus using the detection method.
