The invention provides a connection topology of a power supply and an emission array coil based on a switch network, and belongs to the technical field of wireless charging of electric automobiles. The connection topology comprises n array coils with resonant capacitors {P1, P2 until Pn}, m power supplies {a power supply 1, a power supply 2 until a power supply m} and two sets of switch networks which are subordinate to each power supply, wherein m and n are both integers greater than 2; the connection topology is applied to the field of dynamic wireless charging of the electric vehicle, and the problems that current closed-loop control in a multi-parallel array coil in the prior art cannot be independently achieved, the system power supply is relatively high in cost, the power switch canbe easily damaged, the service life of the power switch is shortened, and the like can be solved.
