摘要
An isolated flyback voltage-multiplier (VM) converter is presented in this study in light of the basic line frequency voltage-multiplying rectifier. The proposed circuit with a high conversion ratio operates in discontinuous conduction mode and combines the merits of the VM with flyback converters. It is very suitable to be used in low-voltage input and high-voltage output applications where compact size and a high conversion ratio are needed. The operations and prominent characteristics of the circuit are described, and the dynamic and steady-state transfer function of the output-voltage/input-voltage is also derived. A laboratory prototype has been built based on the analysis. The validity of analysis for this circuit is verified by experimental results.
