摘要： A triggerable power transmitter for power transmission from a primary coil to an inductively coupled secondary coil in a power receiver has a primary coil; a driver for electrically driving the primary coil; a probing coil receives analog signals indicative of resonance properties of the primary coil; analog filters may be used to filter frequencies, and a processor capable of generating digital information in response to the analog signal and determining if said primary coil is coupled to a secondary coil based on the digital information, and triggering power from the primary coil to said secondary coil when said primary coil is inductively coupled to said secondary coil. A resistor may be selectably connected in series with the primary coil and shorted out when power is transmitted.
