The apparatus comprises an adjustable impedance circuit configurable to be connected to a power source. The apparatus further comprises a transformer coupled the adjustable impedance circuit. The apparatus further comprises a sensing circuit configured to sense a parameter indicative of a parasitic impedance of the adjustable impedance circuit. The apparatus further comprises a driver circuit configured to drive the transformer with a signal based on the sensed parameter that causes the transformer to apply a first voltage to the adjustable impedance circuit. The first voltage has a substantially same amplitude as a voltage drop caused by the parasitic impedance. The second voltage is out of phase with the voltage drop. The sensed parameter is a current circulating in the adjustable impedance circuit or a voltage across at least a portion of the adjustable impedance circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for tuning a resistance and reactance of a wireless power transmitter testing unit","description":"An apparatus for testing an impedance range of a wireless power transmitter is provided.
