Title:
POWER SUPPLY UNIT FOR AEROSOL GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/281753
Kind Code:
A1
Abstract:
This power supply unit 100U comprises: a coil 106 for producing an eddy current in a susceptor 110, which heats an aerosol source 112, by using electric power supplied from a power supply 102; a conversion circuit 132 connected between the coil 106 and the power supply 102, the conversion circuit 132 converting a direct current supplied from the power supply 102 to a pulsating current; an induction heating circuit to which the pulsating current converted by the conversion circuit 132 is supplied and in which the coil 106 is included; a first detection circuit that is capable of detecting information corresponding to the induction current produced using the coil 106; a second detection circuit that is capable of detecting the impedance of the induction heating circuit; and a control unit 118 configured to be capable of controlling the supply of electric power from the power supply 102 to the coil 106 on the basis of the output of the first detection circuit and the output of the second detection circuit.
