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