This paper examines the family of high gain DC-DC converter derived from I-IIA configuration, primarily based on Reduced Redundant Power Processing (RRPP). The primary intention of this study is to determine the best topology for high voltage applications. The steady-state analysis of the proposed topologies is investigated and verified. The denominators of the voltage conversion ratio are observed...
This paper proposes a dual input high step-up boost converter for grid-connected photovoltaic power generation system. Four different DC-DC converters are considered for analysis. From the result of the analysis, the converter with reduced component count and current ripple is identified and proposed for the grid connected PV power generation system. Next, the mode of operation of the proposed converter...
This paper proposes a modified quadratic boost converter with high efficiency and reduced cost. This converter mainly comprises of the quadratic part. The newly proposed converter in this paper is compared with a quasi z source converter which is a quadratic boost converter. The current ripples, cost, efficiency, losses and the complexity of the converters are considered. The steady state analysis...
Multi-port converters have fewer components count and less conversion stage than the traditional power processing solution which adopts several independent two-port converters. This paper emphasis on the use of a single power processing stage to interface multiple power inputs integrates power conversion for a hybrid power source. The classification of various multiport dc-dc converters topologies...
This paper introduces a high gain DC-DC converter for HID lamps used in automotive applications as head lamps. A family of coupled inductor based high step-up converters is introduced and their voltage conversion ratio is derived. In the proposed topologies, a topology with minimal component count is selected and analyzed completely. Steady state analysis of the converter is studied and it is compared...
This paper presents efficiency comparison of quadratic boost converter in continuous conduction mode (CCM) and discontinuous conduction mode (DCM). Analytical expression for the DC component and RMS component of currents in CCM and DCM is derived. Total losses incurred in quadratic boost converter are calculated. Discontinuous conduction modes in three cases are discussed. The simulation result in...
