title = "A 6.78MHz Wireless Power Transfer System with Maximum Power Tracking over Wide Load Range",
abstract = "A 6.78MHz wireless transfer system with a maximum power tracking controller (MPTC). The controller effectively tracks the maximum power points over wide loading range, and lessens the output voltage ripples at the same time. Thus, the size of capacitors at the output of the rectifier can be reduced while achieving high overall power efficiency over wide load range. This chip is manufactured in UMC 0.18 μm 1P6M CMOS process. Measurement results show that the overall power efficiency is maintained above 29% with a load impedance ranging from 80 Ω to 500 Ω. At a load impedance of 500 Ω, the overall power efficiency is higher by 14%, compared to that without the proposed MPTC. This chip occupies 0.93 mm2 and the power conversion efficiency is 78%.",
