Abstract :
In paper (IEEE Trans. Power Electron., vol. 22, no. 1, pp. 69-79, Jan. 2007), large signal and small signal transfer function models of dc-dc power converters are obtained using concept of energy factor (EF) and its associated parameters. In sections II-D and II-E of the original paper, authors describe that the two key parameters of the transfer function are independent of conduction duty cycle k. This is not true and the correct small signal analysis is also reported.
