“…The state-space averaging technique offers accurate results in determining frequency response characteristics and stability analysis of dc-dc power converter. It yields the average output response with respect to the signal switching behaviour (Babaei and Mashinchi, 2013; Middlebrook and Cuk, 1976; Hammoda et al , 2014; Yang et al , 2012). The modelling of power converter using state-space averaging technique provides a small signal linear dynamic model of the converter, which helps in determination of transfer function used for feedback control design (Eng and Chanin, 2008; Murthy and Badawy, 2017; Bhaskar et al , 2014; Shahriman et al , 2018; Martinez and Medina, 2010; Thuttampatty and Chinnathambi., 2017).…”

Purpose The purpose of this paper is to propose a mathematical model for voltage super-lift dc-dc power converter in continuous conduction mode (CCM). Using the presented mathematical model, the analysis of dynamics of power stage for voltage super-lift dc-dc power converter can be performed. Design/methodology/approach The proposed method is based on the average state space model using the state equations of the dc-dc power converter. In the proposed method, the converter is represented as a set of differential equations derived for each switching state of the power switch in terms of inductor current and capacitor voltage. The proposed method describes the dynamic behaviour of the system. The controller is designed to meet performance requirement of the system such as to maintain the dynamics such as stability, steady-state accuracy and the speed of response of the system. Using the obtained model, the analysis of dynamic response of the voltage super-lift dc-dc power converter can be performed. Findings The converter is modelled and verified using conventional circuit analysis method employing state-space averaging technique, and their corresponding transfer function is also derived. The dynamics of the converter is investigated using frequency response characteristics obtained using MATLAB programming environment. In addition, to improve the stability of the converter, proportional-integral controller is designed using Ziegler–Nichols tuning rules, and the effect of the compensator in the plant is also investigated. Originality/value The proposed method can be used for analysing the dynamics of power stage for voltage super-lift DC-DC power converter.

“…The non linear nature due to input and load variations is overcome by constant frequency sliding mode controller .It improves the performance and regulates the output voltage [12]. DC-DC converters are estimated based on the energy factor to obtain the model and second order transfer function for n number of capacitors and inductors [13]. Increase in the efficiency of the converter is achieved by minimizing the switching loss by operating the switch at the lower frequency than the actual.…”

In order to meet the increase in energy demand globally it is necessary to harness renewable energy at its maximum potential for the purpose of electric power generation. For the achievement of high output voltage and efficiency DC-DC converters plays a vital role in low voltage PV array and fuel cells. LUO converters are gaining importance because of geometric progression output. . LUO converters find its application because of high transient performance of the system, high power transfer gain, efficiency and reduced ripple .Because of load and line disturbances the output voltage of DC-DC converter must be operated in closed loop mode. This paper interpolates multitudinous controller for positive output elementary super lift LUO converter (POESLL). The pursuance of the converter under manifold such as variation in input, load are developed and compared for current mode controller and SMC.
