History of Fuji Electric

"Fuji Electric Manufacturing Co., Ltd." was established as a capital and technology alliance between Japan "Furukawa Electric Co., Ltd." and German "Siemens AG". The company name derived from these two companies' first sound "Fu" and "Si"and the highest mountain in Japan, Mt. Fuji.

Imported mercury-vapor rectifier first in Japan and launched production in Kawasaki factory. Market share was high and contributed for transportation infrastructure organization.

Established "Fuji Tsushinki Manufacturing Co., Ltd."(present "Fujitsu Limited") by spinning off the Telephone Department

Introduced technologies from "Voith Hydro Holding GmbH & Co. KG", and delivered the first hydraulic turbine to "Kaminoshiro power plant".

Devised a design and realize microminiaturization.

In response to exploding demand for televisions and radios, Fuji Electric began volume production of selenium rectifiers, electronic components that convert alternating current (AC) to direct current (DC). The company soon took an 80%-90% share of the domestic selenium rectifier market.

Signed a contract with "Siemens AG" for technology transfer of the steam turbine manufacturing. Subsequently delivered the first super-critical, variable pressure turbine in Japan, which was one of the largest in the country at the time. This move to import European technology marked a change of tack in a domestic power generation market dominated by US technology.

Fuji Electric's propulsion system played active roll because of its speedy forward and backward proplusion functions. It enables to gain great propelling power from low speed.

Used know-how as a vendor of refrigerated milk showcases to move into vending machines. Delivered 230 beverage vending machines to the 1970 "Osaka World Exposition", prompting the wider spread of domestically made vending machines.

First in the industry to develop general-purpose inverters. Led the market in creating smaller, more responsive and functional components, resulting in their adoption in a range of fields due to their energy-saving characteristics.

Installed the state of the art PLCs and mini computer which are rare for ships at the time and solid-state relay sequence and centered and automated monitoring systems. Realized durability for severe environmental conditions such as high temperature and high humidity around the equator, impacts and vibrations from advancing frozen seas etc.

Realized small and noise resistant UPSs by modifying MOSFETs for main circuit switching element. At the same time, utilized voltage dip controlling technology as frontrunner of the industry.

PLCs plays active roll in factory automation control equipment. Fuji Electric standardized networking function to PLCs for the first in the industry and was well-received.

Sales of electrical/electronic machinery and components in Europe and Africa.

The launch vehicle’s power control unit was fitted with an aerospace power transistor made by Fuji Electric.

Manufacture and sales of measurement and control devices in Europe, Africa and Middle East.

Delivered the first fuel cells to domestic gas company. Since then, fuel cells installation spreads widely into hotels, education facilities, research facilities, hospitals, office buildings and overseas facilities.

Realized the world smallest and lightest power supply inverter systems. Received the Good Design Award in the year.

Delivered Japan’s first fuel cell cogeneration system (incorporating two 100kW fuel cells) powered by digested sewage sludge gas.

Manufacture of semiconductor devices in Malaysia.

It reduces the power loss of power conversion equipment including power supplies and invertors and a New 3-Level Power Module. It applied power conditioners for renewable energy sources such as photovoltaic power and wind power, UPS and inverter.

The Fuji Electric has been developing its geothermal power generation business since the 1970s in Southeast Asia, New Zealand, the United States, Iceland, and other countries around the world, and has succeeded in installing numerous geothermal power systems.

Charging and CAN communication control which is core of the CHAdeMO standard, is developed by condensing know hows of electric distribution and control technologies and energy management system's information control technologies.

Delivered micro-grid systems to outlying islands. The systems stabilize electric system by controlling fuel cells' random discharge, generated from photovoltaic generations and wind power generations.

We realize the volume of conventional about 1/4 and there are few electricity losses and develops the SiC module which can plan high efficiency of the power control.

The FRENIC 4800VM5 employs a water-cooling system to reduce the heat generated by conversion circuits. Compared to conventional air-cooling systems, the method achieves greatly improved cooling efficiency and allows the capacity of high-voltage inverters to be increased while their size is reduced.

Feature a slim design that allows the units to be mounted against a wall and produced as specialized equipment loaded with the standard functions required to independently operate fans and pumps in air-conditioning equipment and water supply and drainage facilities.

SiC-SBD was fitted with power conditioner systems and UPS.

Fuji Electric commercialized the world’s first three-level module in which a new RB-IGBT and an existing IGBT are integrated in one package. Achieving world highest efficiency of 98.5% (DC 1,000 V product).

Powerless container; D-Box enables constant temperature control and traceability, providing customers with low-cost operations and marketing strategy options.
