- Resonant-Frequency-Tracking Δ-Σ Pulse-Density-Modulation ZVS Class-D Converter for Inductive Power Transfer Applications
抄録
<p>This paper presents a new power control methodology for an inductive power transfer (IPT) system. The switching frequency of a class-D high-frequency inverter is adjusted in accordance with the variations in the resonant frequency due to the vertical and lateral displacements between the transmitting and receiving coils. Then, the output power is controlled byΔ-Σ signal transformation-based pulse density modulation (PDM). The feasibility of the proposed system is revealed through an experiment with a 400W-500kHz IPT prototype, in which the actual efficiency can be maintained over 80% for 20%-30% gap-length variations of the coils.</p>
