【Abstract】 In this paper, the theory of peak current controlled double frequency BUCK converter is described firstly. Based on this, the performance of this converter was analyzed in detail. The rule of how to establish the value of the low frequency inductor is proposed by analyzing the power transmission road of the converter. Especially, the sub-harmonic oscillation of the low frequency inductor current is analyzed and the method to solve this problem is proposed. Finally, the experimental results are given to prove the correction of the theory analysis.更多还原
