Title:
MEASUREMENT SYSTEM FOR DESIGNING RECTIFYING CIRCUIT FOR WIRELESS POWER TRANSMISSION, MEASUREMENT METHOD AND CALIBRATION METHOD
Document Type and Number:
Japanese Patent JP2021056024
Kind Code:
A
Abstract:
To solve a problem in that, in order to measure impedance and power simultaneously during the application of a large amount of power, a method using a vector network analyzer (VNA) is conventionally most general, but the VNA that enables the application of the large amount of power is expensive exceeding ten million yen.SOLUTION: A measurement system 1 for designing a rectifying circuit for wireless power transmission comprises: an AC power source 2; a directional coupler 3 connected to the AC power source 2; a DUT 4 coupled to the directional coupler 3; and an A/D converter coupled to the directional coupler 3; wherein a reference surface 6 is defined between the directional coupler 3 and the DUT 4.SELECTED DRAWING: Figure 1
