A Power Converter Based on the Combination of Cuk and Positive Output Super Lift Lou Converters: Circuit Analysis, Simulation and Experimental Validation

Abstract

This paper has proposed a novel transformerless high gain DC-DC converter. The combination of the Cuk and positive output super lift Luo converter (POSLL converter) has formed the topology of the recommended topology. The continuous input current, the low normalized value of the current/voltage stresses of the semiconductors, the low dimension of the topology due to less stored energy, the common ground point of the input/output terminals, and the high efficiency besides the high voltage gain are the bold features of the proposed topology that makes it suitable for applying in renewable applications and High-intensity discharge lamps (HID). Such a topology has been designed for a continuous conduction mode. However, the function of the converter has been explained in both continuous/discontinuous conduction modes (CCM/DCM). The governing equations of both ideal/non-ideal states have been reported. Moreover, the recommended topology with the recently suggested high gain topologies has been compared in both the ideal/non-ideal modes. The simulation and experimental outcomes have been reported at the end of this study. The simulation in PLECS and experiments on a 120 W prototype have led to substantial results that confirm the validity and applicability of the theoretical analysis on the proposed converter.
