1. A dynamic wireless power transfer transmission system, comprising:
a signal receiver configured to receive, from a dynamic wireless power transfer reception system, a first signal including first information indicative of a location of a first array of coils of the dynamic wireless power transfer reception system;
a second array of coils;
an array of switches configured to connect an alternating current source to the second array of coils; and
a controller configured to:
define a first set of coils of the second array of coils to include a first subset and a second subset, the first subset including the coils that are completely overlapped by the first array of coils, the second subset including the coils that have a degree of overlap, by the first array of coils, that is greater than a threshold degree, but less than completely overlapped,
control, according to the first information, positions of switches of the array of switches, and
control an amount of current conveyed through the second array of coils so that an amount of current conveyed through the second subset is greater than an amount of current conveyed through the first subset.
