AB - In this paper, we analyzed the problems that arise when applying SMPS, which is currently used in most electronic devices due to its low price and miniaturization characteristics, to high-power audio systems. The analysis results confirmed that the characteristics of the audio output are different from the voltage maintenance characteristics of the SMPS, and this is particularly evident in bass impact sounds.
Therefore, it is inevitable to use a large-capacity capacitor, and to solve the rush current problem at this time, a method of constant current control by applying a secondary PWM circuit was proposed. To verify the validity of the proposed method, an experimental circuit was constructed and an experiment was conducted. As a result, it was confirmed that a large-capacity capacitor was charged quickly without exceeding the rating of the SMPS.
