Title:
PELTIER ELEMENT CONTROL DEVICE, ELECTRICAL DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/218920
Kind Code:
A1
Abstract:
This Peltier element control device is equipped with a drive circuit, a voltage detector and a control circuit. The drive circuit supplies an electric current to the Peltier element. The voltage detector detects the voltage value of the voltage to be applied to the Peltier element. The control circuit controls the drive circuit so as to supply an electric current of a pre-determined fixed value to the Peltier element, and so as to reduce the size of the current to be supplied to the Peltier element when a value pertaining to the voltage value detected when the current of the fixed value is supplied to the Peltier element increases.
