【Abstract】 In this paper,the initial value of LLC resonant converter’s inductance current over one period is characterized by approximate expression through time-domain analysis.The estimation results show that the initial value of resonant inductance current only relates to LLC resonant converter’s structure and the output voltage.At last,the correctness of theoretical analysis is validated by simulation and experimental results.更多还原
