Zusammenfassung: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.
