TLDR
The small-signal model of single voltage multiplier high voltage gain dual input boost DC-DC converter is presented which ensures proper voltage regulation by controlling the duty cycle of switching the two sources.Abstract:
This paper presents the small-signal model of single voltage multiplier high voltage gain dual input boost DC-DC converter. The model is developed with parasitic parameters by the state space averaging technique followed by small-signal linearization. For this nonlinear and non-minimum phase converter an inner current loop and outer voltage loop control strategy with PI and compensators are designed in MATLAB. Simulation results corresponding to a step load change between 50 % and full load are presented which ensure proper voltage regulation by controlling the duty cycle of switching the two sources.read more
