AI Technical Summary
Technical Problem
The existing aerosol generation device has low energy efficiency during operation and cannot effectively reduce energy losses.
Method used
By changing the operating mode of the power converter that provides alternating current to the induction coil, multiple switching elements and controllers are used to control the frequency and duty cycle of the current, thereby adopting high-power and low-power operating modes in the preheating and smoking intervals, respectively.
Benefits of technology
It realizes rapid preheating in the preheating interval and maintaining temperature in the smoking interval, while maximizing energy efficiency, reducing the use of additional power, and preventing battery overload.

Abstract
The present invention relates to an aerosol generating device, comprising: a battery, which supplies direct current, a power converter, including first and second switching units, which convert direct current into alternating current and perform switching operations to operate in one of a first mode and a second mode, a heating unit, which applies an alternating magnetic field to a heat-sensitive body according to the alternating current to heat the heat-sensitive body, and a controller, which sends a first switching signal for operating in the first mode at a first heating time and a second switching signal for operating in the second mode at a second heating time to the first and second switching units to control the intensity of the alternating magnetic field; the controller is also configured to control the current supplied to the heating unit and limit the upper limit of the current supplied to the heating unit in a partial interval of the first heating time when the duty ratio of the switching elements respectively included in the first and second switching units in one switching cycle or the current frequency output from the power converter is fixed so that the temperature of the heat-sensitive body reaches a target temperature.
