Abstract: A wireless power transfer apparatus includes a first control system, a first energy transmission system, and a second energy transmission system. The first control system is coupled to the first energy transmission system, and inputs an energy transmission signal to the first energy transmission system. The first energy transmission system is coupled to the second energy transmission system, and inputs some of the energy transmission signals obtained from the first control system into the second energy transmission system. Both the energy transmission signal obtained by the first energy transmission signal from the first control system and an energy transmission signal obtained by the second energy transmission system from the first energy transmission system supply power to a target device.

Abstract: This application discloses a correction and testing system, comprising a first phased array, a second phased array, and a test instrument, wherein the first phased array comprises a first radio frequency RF channel, the test instrument is configured to: determine, based on a coupling signal, an amplitude deviation value and a phase deviation value that correspond to the first RF channel; if the amplitude deviation value and the phase deviation value satisfy a preset error correction condition, correct an amplitude coefficient and a phase coefficient that correspond to the first RF channel to obtain a target amplitude coefficient and a target phase coefficient; and measure performance indicator parameters of the first phased array by using the target amplitude coefficient and the target phase coefficient. The correction and testing system can improve test efficiency, reducing a floor area, and lowering costs.
