摘要： One or more techniques and/or systems are provided for transferring power and/or information between a stator and a rotor. The rotor includes a high voltage rectifier filter and an auxiliary regulator coupled to a power transfer apparatus (e.g., rotary transformer). The high voltage rectifier filter is configured to receive a first electrical signal, associated with a first voltage, from the power transfer apparatus and to generate a second electrical signal, associated with a second voltage, based on a frequency and/or an amplitude of the first electrical signal. The auxiliary regulator is configured to generate a third electrical signal based on the first electrical signal, where a third voltage associated with the third electrical signal is generated independent of the frequency and/or amplitude of the first electrical signal. A single bi-directional data link is used for control and/or communication between the stator and the rotor.

摘要： An inductive power transfer circuit comprises an inductive rotary coupling with a primary side rotatably arranged a secondary side. The primary side has a primary winding and the secondary side has at least two secondary windings. The secondary windings deliver a signal with the same phase and are connected at one end to a pair of capacitors, being further connected to a positive output and a negative output. The other ends of the secondary windings each are separately connected to a pair of rectifiers connected in forward direction to the positive output and in reverse direction to the negative output. By paralleling multiple secondary windings and rectifier circuits, the stray inductances and capacitances can be reduced which further leads to a reduced base load which helps to reduce total energy consumption of the circuit.
