Capacitive wireless-power-transfer technology has the potential to overcome the power, distance, and orientation limitations of inductive power-transfer systems, such as Qi technology. Comparing ...

This tutorial will showcase how inductance, capacitance and resistance affect alternating current. A circuit may have the alternating current through it and the voltage across it rising and failing ...

In technical terms, inductive coupling is the transfer of energy from one circuit to another by virtue of the mutual inductance between the circuits. In an RFID system that uses inductive coupling, ...

Variable current will generate inductance, capacitance, and their related properties of inductive and capacitive reactance. Although there's no energy loss that directly results from these properties, ...

If resonant wireless power transfer (WPT) systems are to fulfill their promise for charging electric vehicles and other high-power applications, there is an engineering issue that must first be ...

These additions to the WIS family allow power and signal coupling to be transferred across an air gap of up to 20 mm. Related To: Pepperl+Fuchs, Inc. These new flat pack wireless devices allow sensors ...
