WIRELESS INDUCTIVE POWER TRANSFER. |
摘要 |
A power transmitter (501) transfers power to a power receiver (505) using a wireless inductive power signal between inductors of the devices. In the power transmitter (501) a power source (601) provides a power source signal which may have level variations. A power signal generator (603) generates a drive signal from the power source signal by means of a frequency converter (605) which increases the frequency of the drive signal relative to the power source signal. A limiter (607) for restricts the power of the drive signal fed to the inductor (503) to be below a threshold in repeating time intervals. A synchronizer (611) synchronizes the repeating time intervals to the power source signal. In the power receiver(505) a load coupler (1001) decouples the power load (1003) from the inductor (507) during the repeating time intervals and a synchronizer (1005) synchronizes the repeating time intervals of the receiver to the power signal. Communication units (609, 1007) exchange data during the repeating time intervals. |
