Ppt Capacitive Power Transfer For Contactless Charging Powerpoint Capacitive cpt works by using capacitive plates on both the charger and receiver such that a capacitor is created when the charging circuit comes in proximity with the charger circuit (fig. 2). [12,13] a high frequency alternating current on the charger end therefore causes an alternating current through the charging circuit, which can then be stored in a battery or used. The simplicity and low cost of capacitive interfaces makes them very attractive for wireless charging stations. major benefits include low electromagnetic radiation and the amenability of combined power and data transfer over the same interface. we present a capacitive power transfer circuit using series resonance that enables efficient high frequency, moderate voltage operation through soft. Power transfer over small capacitors is enabled by. zero voltage switching. enable moderate voltage, high frequency operation. automatic tuning. robust to changes in coupling capacitance. duty cycle adjustment without rx feedback. preserve efficiency at light loads. 3 capacitive wpt. wireless capacitive power transfer (cpt) technology has been proposed recently as an alternate contactless power transfer solution [9 12]. as illustrated in fig. 7, the cpt interface is constructed around a pair of coupling capacitors. the remainder of the power conversion system, including the inverter and rectifier.

This sub section quantifies the power transfer through the capacitive plates as a function of inverter input voltage and dc output load. the impact of the capacitor parameters on power transfer is also explained. the following power transfer analysis assumes an ideal lossless circuit, as shown in fig. 1c. The simplicity and low cost of capacitive interfaces makes them very attractive for wireless charging stations. major benefits include low electromagnetic radiation and the amenability of combined power and data transfer over the same interface. we present a capacitive power transfer circuit using series resonance that enables efficient high frequency, moderate voltage operation through soft.
