Received Jan 15, 2017 Revised Mar 15, 2017 Accepted Mar 29, 2017 In high power DC applications, the single-phase DC-DC converter will face large voltage and current stress in each control switch and thereby the power handling capacity is less. To overcome this problem, three-phase DC-DC converter is used and it is suitable for high power applications with reduced number of switches as compared ...

As worldwide energy consumption continues to increase, so does the demand for renewable energy sources. The total available wave energy resource for the United States alone is 2,640 TWh/yr; nearly two thirds of the 4,000 TWh of electricity used in the United States each year. It is estimated that nearly half of that available energy is recoverable through wave energy conversion techniques. In t...

This paper presents a vector current controller (in the synchronous reference, or dq, frame) with negative-sequence injection capability for three-phase grid-connected converters. is desired operation of converter during unbalanced conditions and also certain type islanding detection. The proposed first determines double-frequency references then uses sixth-order two-input two-output proportion...

In this paper, a new transformerless buck-boost converter based on ZETA converter is introduced. The proposed converter has the ZETA converter advantages such as, buck-boost capability and input to output DC insulation. The suggested converter voltage gain is higher than the classic ZETA converter. In the presented converter, only one main switch is utilized. The proposed converter offers low v...

In this project reduced switching losses and high efficiency is proposed for quasi resonant converter. An AC/DC quasi resonant converter with push pull topology is coupled to two distributed boost inductors into a single magnetic core which hereby reducing the circuit volume and the cost are the development targets of switching power supply today. The quasi resonant converter has ideally zero s...

Abstract In this work, a single degree of freedom resonant converter model is proposed and theoretical studies the are carried out. The suitable for waves with height up to 2 m period 5 seconds, such as on western coast Black Sea. It shown that at resonance its power increases significantly approaches values swell. high (up m) efficiency decreases, but remains relatively constant equal about ha...

A non-isolated DC/DC converter with high transfer gain is proposed in this paper. The presented converter consists of the switched inductor and three-level converters. The DC/DC power converter is three-level boost converter to convert the output voltage of the DC source into two voltage sources. The main advantages of DC/DC converter are using low voltage semiconductors and high gain voltage. ...

High performance cloud computing enables many key future technologies such as artificial intelligence (AI), selfdriving vehicle, big data analysis, and the internet of things (IoT), using clustered CPU and GPU servers in the datacenter. To improve the power efficiency and the infrastructure flexibility, the computing industry is adopting 54VDC to power the servers in the open compute racks. In ...
