The paper is devoted to some problems of multi-coil wireless power transfer (MC-WPT) systems. It is well known that the effective gap for MC-WPT systems can be extended for relatively long distances preserving high efficiency. The paper is organized as follows. In Section 2, the system is described by a matrix model. This model is prepared to determine system properties. In Section 3, the optimization procedure which allows improving the system performance at the desired operating point is introduced. Section 4 contains the results of experimental verification. Moreover, the paper presents an interesting phenomenon of the current unbalance among the system coils.
