Title:
HEATER HEATING CONTROL DEVICE, HEATER HEATING CONTROL METHOD, AND HEATER HEATING CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/092142
Kind Code:
A1
Abstract:
Conventional control devices have posed a problem in that the devices involve a large mounting volume. A heater heating control device according to the present invention has: a drive circuit (21); a first switch (SW0) for selecting either one of a battery voltage (Vbat) and a capacitor voltage (Vc1) so as to apply the selected voltage to the drive circuit (21); a capacitor (24) having one terminal from which the capacitor voltage (Vc1) is outputted; a second switch (SW2) for selecting either one of a ground voltage and a battery voltage (Vbat) applied from the outside as to apply the selected voltage to the other terminal of the capacitor (24); and a control unit (22). The control unit (22) controls the second switch (SW2) so that the battery voltage (Vbat) is applied to the other terminal of the capacitor (24) during a rapid heating period designated by a host system to thereby apply the capacitor voltage (Vc1) to the drive circuit (21). During a steady control period in which a heater (31) is controlled at a temperature of or close to a target value, electric power is supplied from the drive circuit (21) to the heater (31) on the basis of the battery voltage (Vbat).
