Tabuchi company was founded in 1925 with the business domain of silicon steel lamination sheet fabrication.
A lot of manufacturing know-how and method were developed and accumulated during the process where Tabuchi responded the customer requirement of various application of lamination core of silicon steel. The approach was done under the philosophy of "Customer First "
In 1940; Tabuchi transformed itself from a silicon steel lamination maker to transformer manufacturer utilizing lamination steel as the core of transformer. In the late 1950s, volume production of electronics equipment was initiated. During this volume production period, Tabuchi developed many proprietary core technologies as the leading transformer manufacturer; perfect layer-winding technology of round wire. Tabuchi has consistently maintained know how and advanced its art in transformer and coil technology.
Tabuchi amassed the skill, technology and expertise that expanded from its roots in laminated silicon steel and coil winding to include ferrite core technology, and various reactor technologies.
In 1970, Tabuchi expanded our business to Power Supplies utilizing the mainstay of existing business and now Tabuchi has established this SMPS segment as the second core business domain. Tabuchi has been providing analog power solutions that supply many power combinations from a single unit.
Furthermore, Tabuchi entered the business segment of Photovoltaic Inverter where the analog power solution meets the digital control; this segment is classified as the third core business domain.
Since its inception, Tabuchi has consistently expanded its core technology adding the advanced technology to enhance its products and serve its customer base. In short, we are materializing the corporate philosophy “Contributing to the society through the quality manufacturing " in the three core business domains that convert and regulate the electricity.
Tabuchi Technology is based on:
Organic integration of matured core know-how and advanced technologyGreen technology that enables the earth amiable to human. Tabuchi’s energy to meet the demands and requests of its customer base has sustained and consistently expanded its know how and expertise; the respect and honor we have received has hardened our resolve to maintain the core principles that have served us well.
CAE simulation on concurrent engineering is used in various areas such as thermal flow analysis. For example, cooling analysis, such as the picture illustrated above where environmental conditions of the design can be realized.
Tabuchi utilizes wide range of material and device information and sometimes, Tabuchi does technological joint development with material manufacturing companies. Its strategic alliance includes core material, conductors, heat-sink material etc., and spans over the wide range of segments; Tabuchi provides the best power solution to any customers.
Examples of Tabuchi Technology:
Tabuchi's inverter technology for photovoltaic, Fuel Cell or Hybrid/electric vehicle (HEV) application is the combination of optimum integration of Tabuchi's expertise such as: highly efficient magnetics, soft switching, vertical packaging, embedded DSP software and PV simulation. To optimize the efficiency, cost, EMI, reliability, thermal consideration, DC/DC converter topology is unique double resonant circuit and the circuit/CFD simulation is carried out to suppress the power loss of the systems. The system achieves the highest level of PV efficiency in the world and Tabuchi contributes the world in the reduction of carbon dioxides for the environment.
These technologies are attained through the accumulation of energy technology such as SMPS, Magnetics , materials, and many libraries of the Tabuchi's know-how. With these advantages, the PV inverters are ranked #1 in the market share in the world.
In the FPD power supply for High Vision LCD Television, the consumption of electricity shall be minimized both at the stage in normal operation and in the stand-by mode. To countermeasure this requirement, Tabuchi developed special magnetics to be used in composite resonant circuit topologies. Consequently, the system has been made to yield low cost and high efficiency and now the system is reputed by many FPD manufactures in Japan.
Microwave oven technology, Tabuchi is one of the leading manufacturers of high voltage inverter transformers, and is recognized as the leader in this application. We developed a new high temperature microwave oven transformer (pat. p.) under joint development with a material company that incorporates a high temperature insulation system; this transformer is being volume produced in Thailand.
