POWER REGULATION IN WIRELESS CHARGING

摘要

PROBLEM TO BE SOLVED: To provide a wireless charging system that does not cause any problem with initialization even if a received voltage varies.SOLUTION: During an initialization phase, an apparatus for voltage regulation in a wireless power receiver PRU 104 generates load modulation signaling by toggling a power switch, which selectively supplies a regulated voltage to a battery at a regulated current.SELECTED DRAWING: Figure 1
