By monitoring one or more signals within a coil module of the WPT device, this detuning can be detected. Moreover, the WPT system can retune itself by modifying one or more parameters in a transmitting WPT device and/or a receiving WPT device. For example, coil circuits in the transmitting and/or receiving WPT devices can be configured to allow for adjusting of effective capacitance, effective inductance, load resistance, and/or load inductance. In addition, frequency can be modified to permit adjusting power transfer efficiency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for wireless power transfer calibration","description":"In a WPT system, varying parameters, such as coupling coefficient, may cause the system to fall out of resonance and/or tuning.
