The main intention of this paper is to propose a methodology for deriving a reduced-order model from a complex n-dimensional system.The mathematical model for a voltage-lift-based quadratic high-gain dc-dc converter is proposed with tennessee titans dog bandana a reduced-order model in continuous conduction mode (CCM).The chosen topology amalgamates voltage-lift cells with a quadratic boost topology to obtain improved voltage gain.

The operating principle of the configuration with steady-state analysis is discussed in CCM.The state-space averaging procedure and switching flow graph (SFG) obtain the open-loop performance to design a suitable controller for the converter.To reduce the state variables and simplify the modelling, reduced-order modelling is carried out for the topology.

Additionally, the pole clustering method minimizes the converter’s order.The impact of parameter variation with the pole-zero location is discussed elaborately.The Ziegler-Nicholas tuning technique attains the PI controller’s proportional and integral time constant.

The closed-loop response presents better step response output than here the open-loop response.Time-domain parameters are compared for open-loop and closed-loop to validate the controller.Lastly, a 50 W prototype is used for evaluating the converter’s ability at a steady state.
