Manufacturing that we will continue to refine
We were the first to use semiconductors in power supplies for movie projectors. This was the first product we manufactured after our founding. We have been contributing to the movie industry by using electronic control to provide stable light sources. Further, we succeeded in the in-house production of a semiconductor with applications in plating rectifiers and welding machines, thus contributing to the development of industry in Japan as well as Osaka. Currently, we continue to hone the technologies developed in those days and we are a leader in environmentally friendly power supply technologies.
The range of applications has expanded. We provide power supplies for surface treatment, arc generators for welding machines, power supplies for lighting equipment and other equipment, various power conditioners and power supplies for the evaluation of environmentally friendly equipment and equipment applying new energy and highly reliable and customized power supplies which continue to stably support electronic equipment.
Core technologies and advantages
We have been engaged in the manufacturing of power semiconductors for 60 years. We are able to boast to the world about the high reliability of our packaging technologies that are used for the servo drivers of machine tools, which must have high capacity to endure repeated charging, as well as welding machines and PV junction boxes.
What constitute the design and manufacturing of power supplies, which consist of devices and control technologies, are exactly the power electronics technologies that have been attracting attention in recent years as part of national strategies. The power supplies manufactured by the Sansha Electric Manufacturing Group incorporate high-speed digital control technologies. Highly responsive and precise, they are praised by the industry. In addition, their environmental durability, which was fully developed on plating and welding work sites, enables them to be utilized in many settings.
Research and development
Research and development expense
At the Sansha Electric Manufacturing Group, we pursue research into technologies to further improve the reliability and heat resistance of power modules in high voltage and capacity ranges, new bonding technologies, the expansion of applications for SiC devices and next-generation semiconductors, to support social infrastructure.
Further, we will realize electric power conversion technologies that will enable high-speed, high-precision control in addition to compact dimensions and high efficiency. By applying communication and system technologies, we will enable electric power converters to evolve so that they can connect to peripheral equipment.
As an initiative to remain our customers' solution partner, we will use AI in our R&D processes and work on DX and automation in our efforts to reduce development lead time.
Research and development structure
(organization of the Engineering Research and Development Division)
We believe that the teams for developing semiconductors and power supplies in the Engineering Research and Development Division bring about a sense of unity in development from devices to equipment. The organizational structure above is based on the idea that an absence of organizational boundaries will lead to the speedy development of superior products.
Intellectual property
We believe that the unique qualities of the Sansha Electric Manufacturing Group lie in the support for the natural environment and social environment that we provided leveraging our technological strengths, with our intellectual property strategy built on our sales strategies reflecting our understanding of "technology strategy, management strategy and partners' strategies," based on the Global Power Solution Partner concept. Therefore, in our intellectual property strategy, we position intellectual property as management resources for protecting customers' markets and achieving goals together with them, and our activities are focused mainly on creating and maintaining competitiveness. In addition, we will strive to maintain and improve our corporate value and brand through these high-quality initiatives.
Intellectual property activities
The Group implements initiatives to increase its competitiveness, starting from increasing intellectual property awareness and proactively obtaining intellectual property rights to achievements made through various R&D efforts and analyses and protecting and controlling intellectual property rights.
- Actively obtain intellectual property rights for inventions such as innovative new technologies and original designs.
- File applications to secure international intellectual property rights and maintain, manage and control them in accordance with the global strategy.
- To expand business in emerging countries, continuously collect information on counterfeit products to take appropriate measures to address them.
Employee invention incentive program
We have an employee invention incentive program aimed at encouraging engineers to develop inventions and at supporting corporate development and the improvement of individuals' skills by protecting and utilizing their inventions.
Products that contribute to solving social problems.
Contributing to a new energy society through power conversion technology
Hydrogen energy is expected to be a trump card in the fight against global warming as it does not emit CO2 (carbon dioxide) when used. Solid oxide fuel cells, as typified by hydrogen energy, are one of the most efficient fuel cells in terms of power generation efficiency, and are expected to be smaller and cheaper.
Sansha Electric Manufacturing is also actively involved in the development of power conditioners for solid oxide fuel cells.
*What is a power conditioner?
Equipment that converts DC electricity generated from photovoltaic systems and household fuel cells into AC electricity for use in environments such as homes and factories.
Ash-melting plasma power sources for environmental measures related to waste management.
Waste treatment technology using thermal plasma is one technology that can be used to solve environmental problems related to waste and waste treatment generated in daily life and in various other economic activities.
When thermal plasma is introduced into waste treatment, the waste to be treated can be heated to a high temperature in a short time, which reduces the generation of toxic substances such as dioxins and renders them harmless. In addition, the ash from incinerated waste can be melted at an even higher temperature to reduce its volume, which can then be re-used as civil engineering and building materials by turning it into grains known as 'slag'.
Sansha Electric Manufacturing is contributing to the creation of a recycling-oriented society through the development of ash-melting plasma power supplies.
With local communities
Sansha Electric Group's power electronics technology cultivated over many years. Achievements in supporting power energy in all industrial fields. We are making use of these to contribute to the development of future engineers and are working to fulfil our role as a good corporate citizen.
Actions
Factory tour
Since 2018, the Okayama Plant has participated in the Tsuyama Open Factory, which is organised as part of the labour shortage and regional revitalisation of companies in the prefecture. The factory accepts factory tours mainly from elementary, junior high and high school students.
During the factory tours, the fun of manufacturing is conveyed through the experience of making original nameplates using a laser marker, and efforts are being made to nurture the generation that will carry the future.
Sansha Electric Manufacturing will continue to contribute to the local community through participation in such events in the future.
