| 摘 要： | 文章给出一种带辅助变压器隔离型Boost变换器拓扑结构,适合高功率因数校正(PFC)及负载变化范围较宽的场合;考虑到输入输出电压差异较大,引入了变压器;同时针对普通双电感Boost变换器在较宽负载时需采用变频控制的缺点,引入辅助变压器,从而能够实现固定频率控制。

| Abstract: | A double inductor isolated boost converter with the auxiliary transformer is presented in this paper.It can be employed in the power factor correction devices or in a wide load range application.Considering the big difference between the input voltage and the output voltage,a transformer is introduced for isolation.An auxiliary transformer is adopted to overcome the disadvantage that common double inductor boost converter requires variable-frequency control in a wide load range,and then constant-frequency control is achieved.Simulation analysis of the boost converter is carried out. |
