Load characteristics of wireless power transfer system with different resonant types and resonator numbers

Load characteristics of wireless power transfer system with different resonant types and resonator numbers

Wireless Power Transfer (WPT) has been the research focus and applied in many fields. Normally power is transferred wirelessly to charge the battery, which requires specific load characteristics. The load characteristics are essential for the design and operation of the WPT system. This paper invest...
