Cross regulation in flyback converters: analytic model
暂无分享,去创建一个
An analytical model for studying cross regulation among the multiple outputs of flyback converters is presented in this paper. Both the modeling and experimental results show that the cross regulation can be improved by lowering the clamp voltage, which has not been previously reported. Many other factors, such as leakage inductance in primary and secondary windings, magnetizing inductance, and air gap can also affect the cross regulation. Detailed analysis and test results are provided.
