Inductive power supply with device identification |
摘要 |
An inductive power supply system (10) to identify remote devices (14) using unique identification frequencies. The system includes an AIPS (12) and a tank circuit (48) capable of inductively providing power to a remote device (14) at different frequencies, and a sensor (16) for sensing the reflected impedance of the remote device at tank circuit (48). The system further includes a plurality of different remote devices (14), each having a unique resonance frequency. In operation, the AIPS (12) is capable of identifying the type of remote device (14) present in the inductive field by applying power to a remote device (14) at a plurality of unique identification frequencies until the remote device (14) establishes resonance in response to one of the identification frequencies. The AIPS (12) includes a controller (40) that recognizes when resonance has been established by evaluating sensor data, which is representative of the reflected impedance of the remote device (14). Once the identity of a remote device is determined, the AIPS (12) may pull operating parameters for the remote device (14) from memory (24) to ensure efficient operation and to assist in recognizing fault conditions. |
