a minimum phase dc-dc converter with continuous input current and high voltage gain

This paper presents a new high step-up dc-dc switched-mode converter in which not only the input and output ports can be connected to a common ground, but also the service time of the input source is extended due to continuous current injection to the proposed power converter. furthermore, the fast dynamic response is offered by minimum phase characteristics. this key feature is achieved by making the proposed converter’s control to output transfer function, free from the right half plane zero (rhpz). full description of the operation principles, theoretical analysis related to steady-state operation, and also the small-signal modelling derivation of the proposed converter, are presented in this paper. in the end, to confirm all the merits of the proposed converter and accuracy of theoretical analysis, a sample 25 v - 100 v laboratory prototype dc-dc converter with 100w output power has been implemented, and the main experimental results have also been outlined.
