PROJECT TITLE :
Stabilising the output voltage of wireless power pickup through parallel tuned DC-voltage controlled variable capacitor
A new technique to regulate the output voltage of the secondary aspect of an inductive power transfer (IPT) system through a DC-voltage controlled variable capacitor (DCVC) is proposed. As the equivalent capacitance of the DCVC will be controlled by a DC voltage, when it is used as a parallel tuning capacitor at secondary facet of an IPT system, the output voltage can be controlled by this DC voltage through the impact of tuning and detuning. Any, a straightforward proportional plus integral management (PI) controller will be used to generate the controlling DC voltage conveniently to form the output voltage constant. As there's no active switch utilized in the DCVC, it has no switch driving issues such as a high up to twenty V voltage source which is of specific advantage for its application at the secondary side of an IPT system. The DCVC additionally has the potential for use at a lot of higher frequencies than ancient switch mode capacitors as a result of of the smoothness of the adjustment of its equivalent capacitance through a DC voltage.
