1. An aerosol generation system comprising:
a controller for an inhalation device, the controller including a first power supply, a first connector, and a first processor configured to perform energization control of a heater which is used to heat an aerosol source;
a power supply device including a second power supply, a second connector which is connected to the first connector at the time of charging of the first power supply, a second processor configured to perform control of power supply from the second power supply to the controller via the second connector;
a linear regulator on a first line connecting the second power supply and a power supply terminal of the second processor; and
a DC/DC converter configured to convert a voltage supplied from the second power supply and output the converted voltage to the second connector, wherein
a first voltage applied to a power supply terminal of the first processor such that the first processor is capable of performing the energization control and a second voltage applied to a power supply terminal of the second processor such that the second processor is capable of performing the energization control are different from each other, and
the DC/DC converter is not connected to the second power supply via the linear regulator.
