| Abstract |
Inductive power transfer (IPT) is one of the most promising power supply methods for rail transit. Thebidirectional IPT system can fed regenerative braking energy back to the primary side to save electricenergy. However, during accelerating or braking of rail transit vehicle, the output voltage of the IPTsystem usually fluctuate dramatically. The analysis of the existing control strategy shows that there isa large time lag in the regulation of the voltage control loop. This paper proposed a feed-forwardcontrol strategy in which the current of output side capacitor is feed-forward to output voltage controlloop to reduce the fluctuation and recovery time of output voltage. The proposed control strategy isverified by simulation results. |
