OUR
STRENGTH

Fusion ofPower Semiconductors
and Power Supply

Power semiconductors are able to finely control current flow and the up-down of voltage, such as
converting DC to AC. The devices are essential for improving power efficiency and saving energy.
Leading the power electronics industry by providing various power semiconductors and all kinds ofindustrial power supplies from large to small power in Japan and overseas based on the concept of“fusion of power semiconductor and power supply technology”.

Semiconductor

Power supply

The environment surrounding society is undergoing remarkable changes due to the emergence ofpower semiconductors that can handle high power. Our products play an important role in evolving

Since developing a power supply for projector that stabilizes the screen image of a movie theater in
1933, we have provided a wide variety of power supplies such as metal surface treatment, weldingsemiconductor device technology into a wide variety of product groups and supporting the central
part of production facilities and management systems in various scenes.

machines, and power supplies for light source. We support industries with our technology to freely
manipulate and efficiently convert electricity.

High voltage resistance and large current
along with the feature of low loss

Unique process and package
technology for high reliability

Compared to the current mainstream planar typechip in the semiconductor industry, it uses a mesatype chip that has both high voltage resistance andlow loss in the same chip area.

Our unique process and packaging technology
has been highly evaluated in industrial applications
where long-term reliability is required.

Wide range of development from small custommade to large industrial power supplies

High-efficiency power
conversion technology
Our strength is low-loss power conversion technology.
We lead the industry by developing power conditioners
for fuel cell and power supplies for hydrogengeneration equipped with SiC (silicon carbide).

Main application

We will support design and development based on
customer specifications from small custom-madeto large industrial power supplies.

Main application

Thyristor module forindustrial robot

3-phase diode forcommercial air conditioners

High-speed diodefor railway

The power supplies for servo motors used inindustrial robots are frequently turned ON / OFF,so our durable packages adopting transfermold process are used by many customers. It
has been well received by customers especiallyseeking compactness.

Our 3-phase diode which outputs DC current
is small sized and excellent in long-termreliability. This diode is used in inverter circuit
to control motor of electrical equipment suchas commercial air conditioners.

Our high-speed diodes are used as auxiliary
power supplies that are necessary to create incar environments such as railways. In order tohandle large volumes of electricity for lighting, airconditioning and electronic panels and others,
our products have been adopted overseas
as well as in Japan thanks to their great
performance in that field.

treatment

Power supply
for hydrogengeneration

Uninterruptible
power system(UPS)

Metal surface treatment requires efficient andaccurate control of current. Our rectifiers areused in many factories because of their stable
output and long-term reliability.

We develop a power supply for generatinghydrogen expected as next-generationenergy, and a power conditioner for fuel cellthat produces electricity from hydrogen.

Power supply trouble such as power outage
can cause serious disruption to society. Our
UPS protects devices that require high reliability
in every situation from unexpected accidents.
