Comparative Analysis of DC–DC Converter for Application in Energy Systems Based on Renewable Energy Resources
Abstract: This paper is a result of comparative study for seeking the better application of DC–DC converters in renewable energy systems when a transformer is employed in it. It is seen experimentally that by employing transformer with the converter, its output can be made ripple free to a great extent and the efficiency of the system is improved. It was also seen that, by using high-frequency switching devices like MOSFETs and …

Harmonic Analysis of Single-Phase Inverter
Abstract: In this paper, a study is carried out to investigate the total harmonic distortion (THD) of various voltage control signal techniques for single-phase pulse width modulation (PWM) inverter. The inverter is implemented using three PWM techniques—unipolar PWM, modified sine PWM and harmonic injection modulation. The performance of these control schemes are evaluated through simulation in MATLAB/SIMULINK. The obtained THD and fundamental magnitude of the output AC are tabulated (Table 1). …

Grid-Tied PV System with Small DC-Link Capacitor and Low-Frequency Ripple-Free Maximum Power Point Tracking
Abstract: This paper proposes a grid-tied cascaded multilevel inverter (CMI) PV system based on current-fed dual-active-bridge DC–DC converters using small dc-link capacitors. The CMI has many advantages, such as modularity, low harmonic spectra, high ac voltage application with low device rating, and low electromagnetic interference. In addition, distributed maximum power point tracking (MPPT) terminal for segmented photovoltaic (PV) arrays can be achieved by CMI PV converter. The low-frequency ripple-free MPPT is …

A Novel Buck-Boost Converter with an Enhanced Negative Output Voltage
Abstract: This paper proposes the theoretical design of a novel buck-boost converter with an enhanced negative output voltage than conventional converters. It is beneficial for applications that require a wide range of conversion ratio. The steady-state as well as power-loss analyses of the proposed converter operating in continuous conduction mode are examined. Comparison with typical negative output converters like the buck-boost converter, self-lift Luo converter and hybrid buck-boost converter is also …
