A current feedback control method for regulating output voltage among multiple outputs of buck current-fed push-pull converter is presented in this paper.The new control method which can be equivalent with changing factor weighted voltage-mode control method

switch the feedback sampling point from outputs of converter to the input of transformer primary side and compensate the feedback loop with inductor current to achieve the balanced regulation of multiple output voltages.New control method simplifies the feedback loop structure as well as optimizes load regulation of output voltage among multiple outputs in the converter.All the major conduction losses are incorporated in analysis.Finally

the validity of the control method is verified by simulation and experiment results.
