Document Type and Number:
WIPO Patent Application WO/2019/123912
Kind Code:
A1
Abstract:
[Problem] To provide a power supply device for a vehicle-mounted compressor control substrate, with which it is possible to reduce the number of components, achieve an efficiency improvement, and mitigate the problem of noise. [Solution] The power supply device is provided with: an insulated transformer 17 including a primary coil 18 and a secondary coil 22; and a single-ended primary inductance converter (SEPIC) circuit including a capacitor 28 connected to the primary coil. A vehicle-mounted battery BATT is connected to the primary coil. The power supply device is provided with: a low voltage-side power supply terminal 33 connected to the primary coil; high voltage-side power supply terminals 13, 14 connected to the secondary coil; a switching element 29 connected to the primary coil; and a power supply controller 31. The power supply controller controls the switching element on the basis of the voltage of the low voltage-side power supply terminal so that the voltage becomes a set value.
