Sanken Power-electronics Platform (SPP)

Core Technology

With the market surrounding us continuing to undergo majorchanges, customer needs are diversifying, and it is becoming
more important than ever to “create what is expected quickly.”
Therefore, Sanken Electric is working to strengthen marketing
functions and speed up development.
We have shifted to a structure that has functions withresponsibility for everything from the development oftechnology for new products to commercialization and mass
production to establish the Sanken Power-electronics Platform(SPP), a platform for sharing development concepts throughout
the entire development and manufacturing process, frommarketing to procurement, development, design, andmanufacturing. The SPP will dramatically reduce development
and production lead time through the use and standardizationof chip packages based on platform development.

Sanken Electric will concentrate management resources on the three businesses of power devices, power modules,
and sensors, which are the Sanken Core, to promote further strengthening of competitiveness and improvement ofmanagement efficiency, as well as transform ourselves into a company that can grow while solving social issues.
We will also contribute to the development of our customers by offering a broad product portfolio based on Sanken
Electric's core technologies, which include cutting-edge electric power conversion and motor control technologies.

Working Environment

Renovating the Office for a More Comfortable
Place to WorkIn 2021,
we began a fresh
start as a specialized
semiconductor
manufacturer.

The Production Development Center was completed in 2021.
The adjacent Technical Center was also renovated in May 2022.
We transformed our previous office setup to create a hot desking workplace with no fixed desks for employees.
We also upgraded the training room on the 2nd floor of the gymnasium in the welfare building with exercise
machines and gym equipment so employees can workout during breaks or after work.
Renovations of the Tokyo Office, Osaka Branch, and Nagoya Sales Office were also completed in April 2024.
