Title:
VIBRATION DETERMINATION DEVICE, POWER SUPPLY DEVICE, AND VIBRATION DETERMINATION METHOD
Document Type and Number:
Japanese Patent JP2018026975
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration determination device, a power supply device, and a vibration determination method, capable of accurately determining whether fluctuation of the current detected by a current sensor is due to fluctuation due to mechanical vibration.SOLUTION: A vibration determination device according to an embodiment comprises a current sensor, a voltage detection unit, and a vibration detection unit. The current sensor detects a current flowing through a current path on the basis of a magnetic flux according to the current flowing through the current path. The voltage detection unit detects a voltage at both ends of a switch provided in the middle of the current path. The vibration detection unit determines whether fluctuation of the current detected by the current sensor is fluctuation due to mechanical vibration on the basis of comparison results between the current detected by the current sensor and the voltage between both ends of the switch detected by the voltage detection sensor.SELECTED DRAWING: Figure 1
