On the derivation of control-to-output voltage of PWM current-mode controlled modular DC-DC converters: A PSIM-supported proof

In this paper we extend our previous work on deriving the control-to-output voltage transfer functions of pulse-width modulated current-mode controlled parallel-input/series-output dc-dc converters that operate in the continuous conduction mode by comparing the analysis results with responses obtained using the “ac sweep” tool available on PSIM simulation software. The topologies considered for the power stage are the full-bridge buck-based, the full-bridge boost- based, and the flyback.
