Abstract

An extension of the equivalent small parameter symbolic method to constant-frequency current-mode controlled converter systems is presented

along with two methods of determining the system's duty-ratio

the precise and the simple methods .It is shown that the former is practical due to its having no assumptions of linear inductor current waveforms and small output ripples

and the latter is useful for simplified engineering analysis.The resulted analytical expressions are helpful to understand the mechanism of the circuit.
