Abstract
A smoking set control circuit for a smoking set includes: a power circuit first and second sampling circuits; a voltage regulating circuit having power tubes; a microcontroller configured to: control the power tubes to work at a plurality of different preset switching frequencies; acquire first electrical parameters and second electrical parameters at different preset switching frequencies, and accordingly determine corresponding efficiencies of the voltage regulating circuit at different preset switching frequencies; control the power tube to take the preset switching frequency corresponding to the highest efficiency among the corresponding efficiencies as the working frequency. A loss of the voltage regulating circuit is reduced and a utilization rate of power supply is improved by acquiring the electrical parameters at different preset switching frequencies, determining corresponding efficiencies of the voltage regulating circuit, and controlling the power tube to take the preset switching frequency corresponding to the highest efficiency as the working frequency.
