This paper presents a comparative evaluation of eight high-voltage step-up converters based on different associations of boost and zeta standard dc–dc pulse width modulation (PWM) cells. These eight converters present different characteristics such as cascaded and stacked PWM cell associations, as well as isolated winding coupled inductors, tapped winding coupled inductors, and noncoupled inductors...
This paper discusses about the partial power processing concept applied to DC/DC converters, which has been presented in the literature as an option to be used on voltage regulators in several applications such as photovoltaic systems. The purpose of this paper is to elucidate the partial power processing concept and demonstrate that, opposing the sense created in the literature, the fact that a converter...
This paper proposed a simple modeling approach for the dynamic analysis and characterization of a family of high step-up DC-DC converters obtained by the integration of standard topologies presented by the authors in a previous paper. Simulations and experimental results are obtained to confirm the reliability of the approach.
This paper presents a systematic methodology to generate high step-up voltage gain converters based on the combination of two standard DC/DC converters. The converters are combined so that their input sections are integrated reducing the converter component count. Their output sections are associated to derive three basic configurations, the series, the parallel and the cascade outputs. The paper...
