The mass usage of traditional fossil energy has adversely affected the environment on a global scale, such as environmental pollution and greenhouse effect. Meanwhile, there has been a growing demand for energy with the development of society. Since traditional fossil energy is not renewable, it is faced with the problem of energy shortage. Solar energy and hydrogen energy are promising, and ph...

This paper presents a new single stage DC-DC multilevel boost converter topology with very high voltage gain ratio. It is a Pulse width modulation (PWM) based switched inductor multilevel boost converter (SIMLC) consisting of two switched inductors, 2N+2 Diodes, 2N-1 Capacitors for N level boost converter. High switching frequency has been used to decrease component size. The proposed converter...

This paper proposes and discusses a novel AC/DC converter suitable for small-scaled wind power generation system applications. By introducing flyback cells into the three-phase single-switch Boost circuit, the proposed converter is designed as single-stage and has both rectification and high step-up power conversion functions. It is able to obtain high voltage gain at low input voltage level, a...

The opening profile of the cracks produced in the Double Cleavage Drilled Compression (DCDC) specimens for brittle materials is investigated. The study is achieved by combining Finite Element simulations of a DCDC linear elastic medium with experimental measurements by crack opening interferometry on pure silica glass samples. We show that the shape of the crack can be described by a simple exp...

Energy shortage and environmental contamination in the present scenario has increased the use of renewable energy sources.Among the renewable energy sources the photovoltaic cells plays a significant role in meeting the energy requirements. The problem associated with the PV cells are it produces low output voltage and thus a high step-up dc dc converter is essential to boost the low voltage of...

In this study, a robust controller for voltage regulation of the POESLL converter worked in continuous conduction mode is presented. POESLL converter is a DC/DC converter with a high voltage gain. DC/DC converters are used in telecommunication systems, power sources and industrial applications. Owing to the switching operation, the structure of the POESLL converter is highly non-linear. In addi...

Microbial population growth is typically measured when cells can be directly observed, or when death is rare. However, neither of these conditions hold for the mammalian gut microbiota, and, therefore, standard approaches cannot accurately measure the growth dynamics of this community. Here we introduce a new method (distributed cell division counting, DCDC) that uses the accurate segregation a...

A novel high step-up DC-DC converter with coupled-inductor and switched-capacitor techniques is proposed in this paper. The capacitors are charged in parallel and are discharged in series by the coupled inductor, stacking on the output capacitor. Thus, the proposed converter can achieve high step-up voltage gain with appropriate duty ratio. Besides, the voltage spike on the main switch can be c...

Abstract— This paper proposes a new type of converter called Single Phase Z-source Matrix Converter (SPZMC). The SPZMC is an ac-to-ac converter device. Simulated using diode bridge bidirectional switch cell. The simulation is performed in different loads with fixed input and variable output frequency. Pulse Width Modulation (PWM) switching strategy is used to obtain the variable frequency. The ...
