Abstract
AbstractAn enhanced pulse density modulation (EPDM) is proposed to optimize the efficiency in inductive power transfer (IPT) systems under various coupling and load. It controls the optimal output voltage without estimating the mutual inductance, which improves the efficiency and eliminates the communication between the primary and secondary side. Further, the four working modes of semi-bridgeless active rectifier (S-BAR) are combined uniformly by the EPDM based on ΔΣ modulation, which increases density resolution and decreases the output voltage ripple. Besides, the soft switching can be ensured by synchronous signals. The effectiveness of the method is confirmed by simulations and experiments.KeywordsInductive power transfer (IPT)Efficiency optimizationVoltage regulationEnhanced pulse density modulation (EPDM)ΔΣ modulation
