Abstract: Inductive-power-transfer (IPT) is widely used in wireless charging of electric vehicle (EV). However, the output power and efficiency of the IPT system are often affected by misalignments. In this article, a double-side- LCC ( DLCC) compensation network with switch-controlled-capacitors IPT topology is proposed to improve the misalignments …

Learn MoreCapacitors are available in a wide range of capacitance values, from just a few picofarads to well in excess of a farad, a range of over 10(^{12}). Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a consequence of Equation ref{8.4}.

Learn MoreFixed capacitors means that you may have to pick certain discrete values so you can decide to leave the load as somewhat inductive (undercompensated) or capacitive (overcompensated). If the load inductance varies during operation then again you may have to pick some intermediate value and the cancellation may be fairly imperfect.
