Abstract: A testing system (90) for use in testing of wireless power transfer is disclosed. The testing system has at least one wireless power receiver circuit (34) for receiving inductive power from an external wireless power transmitter (20). The testing system is arranged to detect received inductive power at least two operating frequencies relating two both a wireless power standard and a wireless communication standard. Measurements data originating from inductive power received adopting the wireless communication standard is forwarded to a processing means (42) which based on reference data is arranged to detect whether a communication receiver circuit (15) and arranged to communicate according to the wireless communication standard adopting the second frequency range, when arranged in operative proximity to the external wireless power transmitter device (20), would be negatively affected by the inductive power transmitted from the external wireless power transmitter device (20).

Abstract: A testing device (30; 50) for testing a wireless power transmitter device (20) having at least one transmitter coil (24), wherein the testing device (30; 50) comprises at least one wireless power receiver coil (34) and wherein the testing device (30; 50) is in operative communication with a processing means (42; 52) and its associated memory (44; 54). The testing device (30; 50) is configured to receive a power signal applied by the wireless power transmitter device (20), transmit a first packet, being a signal strength packet, to the wireless power transmitter device (20) in response to receiving said power signal and transmit a second packet to the wireless power transmitter device (20) if the wireless power transmitter device (20) continues to transmit the power signal to the testing device (30; 50) n response to receiving the signal strength packet.

Abstract: An apparatus and a method for determining a power value of a target in the form of an AC circuit (130; 230; 330) having an AC power source (132; 232; 332). The method involves operating (72) a controllable DC power source (12) to provide DC power to a DC circuit (10; 110; 210; 310) and measuring (73) at least one thermal parameter related to power dissipation of the DC circuit (10; 110; 210; 310) and of the target AC circuit (30; 130; 230; 330), wherein at least one heat sink (160a, 160b; 260; 360) is thermally coupled between the DC circuit (10; 110; 210; 310) and the target AC circuit (30; 130; 230; 330). The method further involves controlling (74) the DC power source (12) based on the measured at least one thermal parameter to reduce a difference in power dissipation between the DC circuit (10; 110; 210; 310) and the target AC circuit (30; 130; 230; 330).
