Abstract
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.
