Wireless power transfer (WPT) is an emerging technology and trending topic in the field of research and commercial area, it provides convenience for electrical users to charge devices by means of avoiding power cables. It has proven to be applicable from low power: mobile devices, to high power: Electric Vehicles (EV), and many other applications for battery charging. During the past, most of research focused on inductive-wireless power transfer. But, recently, capacitive-wireless power transfer (C-WPT) has proven to be efficient over inductive-wireless power transfer for near-field transmission. Capacitive- Wireless power transfer uses electric field to transfer power from transmitter to receiver by means of capacitive plates. In this work, we analyzed the resonant points of a Switch-Inductor-Inductor-Diode (SLLD) circuit. The SLLD circuit has a relatively-simple topology with only one switching device, which makes it obtaining a potential of high efficiency and easy to identify the impact of each component on system performance. The SLLD circuit is applicable for both low power and high power applications. According to the resonant points, the circuit parameters were specified to obtain the controllability of MPPT. The influential factors were analyzed and verified by experimental tests.
