1. A system for dynamic wireless power transfer (DWPT), the system comprising:
a transmitter side configured to wirelessly transmit power to a receiver coil during DWPT, the transmitter side comprising a plurality of transmitter coils; and
a receiver side configured to wirelessly receive power from the transmitter side during DWPT, the receiver side comprising the receiver coil,
the receiver side further comprising a secondary compensation network comprising a compensation inductor integrated with the receiver coil and disposed in parallel with the receiver coil,
the compensation inductor having a same outer length as the receiver coil and a same inner length as the receiver coil,
the system being configured to produce an output voltage, on the receiver side during DWPT, with a fluctuation rate of +/−4% or less, while the receiver side is moved over the transmitter side such that the receiver side receives power from the transmitter side as it moves over the transmitter side,
the compensation inductor being identical to the receiver coil, and
each transmitter coil of the plurality of transmitter coils being identical to the receiver coil.
