Development of Insulated Gate Bipolar Transistor Module for Advanced Neural Point Clamp Circuits by Fuji Electric
Fuji Electric System has announced the development of insulated gate bipolar transistor (IGBT) module for advanced Neural Point Clamp (NPC) circuit series. The new IGBT module features industry’s first 3-level converter circuit in a single package will dramatically lower power loss. The reduction in power loss has been achieved by producing a waveform that is closer to a sine wave than conventional 2-level type module, which is done by expanding the number of output voltage steps to three levels. In addition to this, company has incorporated an RB-IGBT (reverse blocking IGBT), eliminating any needs for a diode for blocking reverse current, resulting in a more efficient operation of converter circuit.

Development of Thermoelectric Waste Heat Recovery Module by AIST
Efficient use of fossil fuels, such as petroleum and natural gas is in everyone’s agenda, more so for Japan that relies heavily on imports for very much most of its primary energy supplies. This dependency is making Japan as well many other countries with substantial energy dependency to focus on power generation using recovery waste heat as a method in increasing energy utilization efficiency. However, recovering waste heat involves many issues including high recovery costs as well as developing new technology to facilitate the recovery to begin with. One technology that has been gaining in popularity for its capability in waste-heat-recovery power generation is thermoelectric power generation, due to its simple system configuration suitable for downsizing. But use of this technology involves improving the performance of thermoelectric materials to achieve electrical conductivity as high as of a metal and thermal conductivity as low as glass. Based on this researchers at AIST has successfully developed a thermoelectric power generation module that can withstand temperature as high as 300 degrees Celsius. Read more
ROHM unveils Industry’s First Compact High-Speed Optical Communication Module
Improved display resolution and camera picture quality as well as capability of video playback on today’s mobile phones making inter-substrate transmission rate among the mobile phone manufacturer an increasingly important characteristic. But the current thin coaxial lines or flexible cables made of copper wiring can handle only about 500Mbps due to various effects such as attenuation and fluctuation from bending. In addition to this shortcoming the copper wiring requires between 40 to 50 wires making it the resulting cable difficult to bend which is an important issue during the assembly. Finally, the connector and cable footprints are large resulting in noise generation or its susceptibility to noise. In order to overcome this, Rohm has developed the industry’s first ultra compact high speed inter-substrate optical communication module capable of transmission rate of 2.5Gbps within portable devices such as mobile phones.

Development of 12.1-inch XGA Color TFT-LCD Module by Mitsubishi
Mitsubishi Electric today made an announcement on development of 12.1 inch XGA color TFT LCD module featuring a reduced size and thickness of 10% and 20% respectively in comparison to the previous model. The new AA121XL01 offers a high brightness of up to 1,000 cd/m2 plus a longer backlight life through incorporation of white LED and its inverter-less construction. The minimum backlight lifespan is 60,000 hours at the 25 degrees Celsius. Additionally, the inverter-less construction helps in eliminating any needs high-voltage inverters resulting in lowering the final product cost. Read more
Development of highly integrated Organic Photovoltaic Module
Sunlight as a clean and inexhaustible source of energy provides an effective way in diminishing the green house effect. Solar Cells or Photovoltaic (PV) serves as a proven technology known for its ability in capturing and reusing sunlight to be used as source of energy, but the cost of generating power with the current PV technology is very high prohibiting the wide spread use of PVs as a result of this. Extensive amount of time has been already gone for research and development of Organic Photovoltaic (OPV) in a promise to provide a much improved sunlight conversion rate. During this research it was discovered that C60 Fullerene offers a very good organic semi-conductivity and it can be applied to the OPV module as an acceptor. The Fullerene was supplied for module production by Frontier Carbon Corporation (FCC) a Mitsubishi Corporation subsidiary and the world’s largest producer of Fullerene. Read more
