LOAD IMPEDANCE DETECTION FOR STATIC OR DYNAMIC ADJUSTMENT OF PASSIVE LOADS |
摘要 |
<p>This disclosure provides systems, methods and apparatus for detecting an impedance of a wireless power transmitter load. In one aspect, a method of determining a reactive condition of a wireless power transmitter apparatus is provided. The method comprises determining a value correlated to a voltage of drain of a switching element (604) of a driver circuit (624) of the wireless power transmitter (600). The method further comprises determining a reactance load (618) change based on the determined voltage.</p> |
