Speech Summary :

Since entering the 21st century, we have been facing a globally urgent need for all nations, without exception, to deal with environmental concerns such as global warming and energy issues arising from the depletion of fossil fuels. One of the solutions is energy-saving technology for automobiles.
The energy-saving approach has so far emphasized individual vehicles, such as hybrids, thus primarily focusing on vehicle energy management for fuel efficiency improvement. However, the emergence of plug-in HVs and EVs mean that we have entered an era of total energy management. We must also consider energy security as a new viewpoint where energy is also provided domestically or through infrastructure.
I will explain the status and future view with the latest examples of electric propulsion for vehicles and total energy management, such as PHV and EV linked to grid.

NTT Activity for Green IT

Mr. Tadatoshi BABASAKI

NTT Energy and Environment Systems Laboratories

 

Tadatoshi Babasaki received the B.S. and M.S. degrees in Electronic Engineering from Nagasaki University in 1988 and 1990, respectively. He joined NTT, Tokyo, Japan, in 1990. He has been engaged mainly in the DC power feeding system and battery for telecommunication. He is a PhD student with Nagasaki University. He is a member of the IEEE.  

 

Speech Summary:

With the increase in the volume of information downloaded in Japan, the power, which is consumed by user terminals and network devices, has been increased. This increase has led to an increase in the emission of carbon dioxide. This is a negative effect of the use of ICT on the environment.
However, the use of ICT has a positive effect on the environment as well. Advances in ICT can reduce the movements of people and improve the efficiency of physical distribution and industry in general.
NTT try to decrease the power of network device, power supply system and cooling system, and calculate of the effect of ICT service on reducing environmental impact. These activity is introduced in this seminar.

Speech Summary:

The induction heating cook tops adapting the power electronics technology, which changes power frequency with semiconductor switching devices, were put in practical use in the 1970s, and have been becoming increasingly popular as energy-saving inverter appliances which replace gas and electric (50/60Hz) cook tops, due to its specific features of safety, cleanliness, quick warming and high efficiency. In this session, the advances of the high-frequency inverter circuit topologies which is a main component of an induction heating appliance and the advances of the power semiconductor switching devices supporting its progressive developments, and the latest technology trends will be explained.

Speech Summary:

Photovoltaic (PV) generation system is one of the most promising methods for achieving low-carbon society and is supported by government schemes like a Feed-in Tariffs (FIT) system throughout the world. It is essential to achieve the “grid-parity”, which is generally referred as the point and time when photovoltaic electricity will become competitive with commercial electricity, for its further large-scale installation. SHARP has been developing many technologies (i.e. improvement of conversion efficiency, reduction of material cost, and so on) to achieve grid parity at the early stage.

Power Electronics for Low-Carbon Industrial Revolution

Dr. Teruo YOSHINO

Technology Executive,

Teruo Yoshino graduated from Yokohama National University, YNU, in Japan with his master degree and joined Toshiba in 1978. Since then, he has been working for the power electronics development. In 2003, he joined Toshiba Mitsubishi-Electric Industrial Systems Corporation, TMEIC, which succeeded the industrial systems business from two major Japanese companies. He earned his doctorate from YNU based on his works in HVDC and SVC development. Recently, he is leading the development on MW-rated converters for renewable energy, solar and wind power, and for energy management, green IT and green factory. Through the power electronics, he hopes to contribute to the sustainable society.

 

Speech Summary:

The power electronics is indispensable for the low-carbon industrial revolution leading to the sustainable society through the renewable energy and the industry greening. The renewable generation facilities are now scaled up above megawatt range. The greening is now expanding to industries consuming power above megawatt range, too. Then, the speech focuses on the very high-capacity power electronics trends for such fields. The speech introduces the power conditioning system (PCS) for photo-voltaic generation, the back to back converter for wind power and PCS for the battery energy storage system. The speech also covers the high-efficiency UPS for the Green IT and the extra-large converters rated at several tens of MW for the Green Factory. Owing to the recent development of the power semiconductor and control devices, even in these high power range, the converter efficiency and the operation flexibility have been remarkably improved compared with the old generation.

One example of the projects related to power electronics is “Development of Inverter Systems for Power Electronics (FY2006-FY2008)”, which realized an inverter system with 70 % energy loss reduction and 1/4 smaller size by utilizing silicon carbide devices instead of silicon devices. Currently new project, “Development of Next-generation Power Electronics Technology (FY2009-FY2012)”, is running aiming at harder targets. We also focus on other wide-gap devices such as gallium nitride devices. We will discuss topics related to power electronics and other activities of NEDO in this session.
