Abstract

The solar powered systems require high step-up converter for efficient energy transfer. For this, quasi-impedance network converter has been introduced. The quasi-impedance network converter (QZNC) is of two types: type-1 and type-2 configuration. Both the type-1 and type-2 QZNC configurations have drooping voltage gain profile due to presence of high switching noise. To overcome this, a new quasi-impedance network converter synchronizing the switching circuit with low frequency noise has been proposed. In this paper, the proposed QZNC configuration utilizes the current controlling diode to prevent the output voltage drop. Thus, the suggested topology provides linear high voltage gain profile, low load voltage ripple, and reduced impedance network stress and device stress. Therefore, the efficiency of proposed QZNC has been improved. The topology description, working principle, parameter design and comparison with traditional converters are illustrated. And finally, both simulation and practical results are presented to confirm the converter characteristics and performance. From the results, it has been found that the performance of the suggested topology is better as it achieves a higher efficiency of 81% and hence, it is suitable for high power applications.
