FREQUENCY CHARACTERISTIC MEASUREMENT METHOD

摘要

A power transmission-side measurement tool is installed in a power transmitting apparatus that applies an AC voltage stepped up by a step-up transformer to an active electrode and a passive electrode. The power transmission-side measurement tool includes a measurement active electrode that faces the active electrode and a measurement passive electrode that faces the passive electrode, and the measurement active electrode and measurement passive electrode are shorted together. Frequency characteristics of a serial resonance circuit formed by leakage inductance of the step-up transformer and capacitors are measured in a state where the power transmission-side measurement tool is placed on the power transmitting apparatus.
