- Booth number 1-W22
We will exhibit its next-generation high-power conversion technology, the Solid State Transformer (SST).
The SST is an advanced alternative to conventional large commercial-frequency transformers, offering significant reductions in size and weight. It addresses longstanding challenges associated with bulky and heavy transformer systems.
Beyond basic voltage conversion and insulation, the SST enables advanced functionalities such as bidirectional power flow control, power factor correction, and sophisticated energy management. It is well suited for emerging power distribution and conversion applications.
The presentation will also highlight practical approaches to thermal management—one of the key challenges in high-power equipment—supported by real-world examples.
This exhibit will provide valuable insights for engineers and professionals involved in next-generation power distribution and energy systems. Visitors are invited to explore the potential of SST technology and its role in shaping future power infrastructure at our booth.

Rotor Position Sensor
-
Sales point (English)
Sumida developed new angle sensor (RPS) which is suitable for motors for electric vehicles. The RPS reads eddy cuurent between sensor and rotor target and the sensor outputs SIN/COS to control unit. The benefits of Sumida RPS is tiny and simple design and the sensor will not be larger no matter motor size and also it just need Vcc 5V and it's very simple design comparing to other solutions.

Wire-wound Contactless Type Current Sensor
-
Sales point (English)
This sensor is capable of sense wide current range and very stable over wide temperatures. One of the benefits of wire wound type is contact less which just puts sensor on bus-bar to sensing the current by very accuracy and stay safe on high voltage line.
This sensor will be demonstrated at our booth.
