Electric mean power is Pc=200kW, belongs to quick charge.
Prior art is reported using parallel radio energy transmission technology, and single inversion source powers, many armature windings work in parallel
The dynamic charging modes of the sectional guide rail modularization of work, transmitting terminal uses an inversion source and multiple transmitter unit parallel-connection structures, often
Individual transmitter unit is made up of control unit, transmitting coil, compensating electric capacity, grammed switch.Control unit is obtained from ac bus
Operating voltage, the transmitting coil that grammed switch is connected works in series resonance, and larger output is obtained by using full-bridge inverting
Power.When electric car is travelled, the energy being wirelessly transferred is used directly to direct current generator on driving car, when electric car enters
During anchor point, the energy being wirelessly transferred is used for being that super capacitor or battery pack charge.But this switched using grammed switch
The mode of transmitting coil is restricted in actual applications, if that is, electric automobile according to 100kM speed per hour, transmitting coil and
The coupling time of vehicle-mounted receiving coil only has 0.043 second, and grammed switch can not meet the switch speed completed needed for coupling time
Degree, and can be limited by grammed switch life-span and security, influence its extensive use.
