Measurement system, measurement method and calibration method for rectifier circuit design for wireless power transmission.

摘要

PROBLEM TO BE SOLVED: To measure impedance and electric power at the same time when a large amount of electric power is applied, a method using a vector network analyzer (VNA) is the most common, but a VNA capable of applying a large amount of electric power exceeds 10 million yen. To be expensive. SOLUTION: The AC power supply 2, the directional coupler 3 connected to the AC power supply 2, the DUT 4 coupled to the directional coupler 3, and the A / D converter coupled to the directional coupler 3 are provided. This is a measurement system 1 for designing a rectifier circuit for wireless power transmission, characterized in that a reference plane 6 is set between the directional coupler 3 and the DUT 4.
