Title:
ON-BOARD AIR CONDITIONER CONTROL DEVICE, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/239714
Kind Code:
A1
Abstract:
This on-board air conditioner control device (1) comprises: a PTC heater (H) which is contained in a high-voltage circuit (HV) and generates heat by means of power supplied from a high-voltage battery (B2); a micro-controller (10) which is contained in a low-voltage circuit (LV) and controls the power supplied to the PTC heater (H) from the high-voltage battery (B2); a current detection sensor (14) which is contained in the high-voltage circuit (HV) and outputs a voltage signal indicating a value for the current flowing through the PTC heater (H); a V/f conversion unit (162) which is contained in the high-voltage circuit (HV) and converts the voltage signal outputted by the current detection sensor (14) to a frequency signal; and a digital isolator (172) which transmits the frequency signal to the micro-controller (10) while preserving electrical insulation between the V/f conversion unit (162) and the micro-controller (10).
