 Abstract —The efficient supply of electric power relies strongly on the selection of suitable voltage levels for different sections of the energy distribution system. When higher levels of power are required, a medium-voltage level in the tens of kilovolts range is typically selected. In accordance to current trends in energy conversion, the supply of power must fulfil several functionality requirements among which high power-quality and access to a low-voltage DC interface can be highlighted. Moreover, low energy losses, high power-density, low failure rate and low total cost of ownership remain as major research challenges. Solid-state-transformers (SSTs) comply with these functionality requirements as well as with the demanded high performance levels while directly connecting to medium-voltage.

A Study on Optimization of Compact High-voltage Generator Based on Magnetic-core Tesla Transformer Young-Kyung Jeong*, Dong-Gi Youn** and Moon-Qee Lee†

Abstract – This paper presents a compact and portable high-voltage generator based on magneticcore
Tesla transformer for driving an UWB high power electromagnetic source. In order to optimize
the performance of the high-voltage generator, a novel open-loop cylindrical magnetic-core adopting
the quad-division lamination structure is proposed and manufactured. The designed high-voltage
generator using the proposed magnetic core has a battery-powered operation and compact size of 280
mm × 150 mm in length and diameter, respectively. The high-voltage generator can produce a voltage
pulse waveform with peak amplitude of 450 kV, a rise time of 1.5 ns, and pulse duration of 2.5 ns at
the 800 V input voltage.

Battery Charging System for PHEV and EV using Single Phase AC/DC PWM Buck Converter Jung-Hyo Lee*, Doo-Yong Jung*, Sang-HoonPark**, Taek-Kie Lee***, Young-Ryul Kim§ and Chung-Yuen Won

1. Introduction
There has been active research to develop environmentally friendly products due to the recent increase in the oil prices and the reinforcement of strict environmental regulations worldwide. In particular, in order to develop environmentally friendly vehicles, there is active research in the automotive industry, which utilizes an immense amount of oil resources, on the drive system using electric motors and power-conversion systems that may potentially replace the conventional internal combustion engine [1, 2]. PHEV(Plug-in Hybrid Electric Vehicle), NEV(Neighborhood Electric Vehicle) and the general EV(Electric Vehicle) are examples of the new ecological vehicles. Such vehicles use electricity as its auxiliary and main power source, and battery is used as the energy source to drive their electric motors.

Multi-physics Analysis for Temperature Rise Prediction of Power Transformer

 

Multi-physics Analysis for Temperature Rise Prediction of Power Transformer Hyun-Mo Ahn*, Joong-Kyoung Kim**, Yeon-Ho Oh***, Ki-Dong Song***and Sung-Chin Hahn

Abstract – In this paper, a method for multi-physics analysis of the temperature-dependent properties of an oil-immersed transformer is discussed. To couple thermal fields with electromagnetic and fluid fields, an algorithm employing a user defined function (UDF) is proposed. Using electromagnetic analysis, electric power loss dependent on temperature rise is calculated; these are used as input data for multi-physics analysis in order to predict the temperature rise. A heat transfer coefficient is applied only at the outermost boundary between transformer and the atmosphere in order to reduce the analysis region. To verify the validity of the proposed method, the predicted temperature rises in high-voltage (HV) and low-voltage (LV) windings and radiators were compared with the experimental values.

Integrated Operation of Power Conversion Module for DC Distribution System HEE-JUN LEE College of Information and Communication Eng. Sungkyunkwan University

 

Abstract - It is DC power that Output of renewable energy being recently developed and researched. Also, demand of DC power will expect to proliferate due to increase of digital load. Thus, DC distribution system providing high quality of power and reliability has emerged as a new distribution system. If the conventional distribution systems are substituted by proposed DC distribution system, the output of renewable energy can be connected with distribution systems under minimum power conversion. Therefore, in the event of connection with DC load, it can construct an efficient distribution system. In this paper, the integrated parallel operation of power conversion module for DC distribution system is proposed. Also, this paper proposed modularization of power conversion devices for DC distribution system and power control for parallel operation of large capacity system. DC distribution system consists of three power conversion modules such as AC/DC power conversion module 2 set, ESS module 1 set. DC distribution system controls suitable operation depending on the status of the DC power distribution system and load. Integrated operation of these systems is verified by simulation and experiment results.
