Diversified applications built on proven power conversion and autonomous control technologies.
Proven Core, Practical Applications
Based on its capabilities in power conversion, control, and embedded design,
THEONE develops industrial equipment and systems designed for practical field operation.
From test and evaluation equipment to reliability inspection systems, control boards, and remote monitoring solutions,
we deliver them in the form required for each customer’s process and operating environment.
Beyond simple delivery, we connect design, fabrication, validation, and maintenance
to reduce operational risk and support stable use in the field.
We design test, evaluation, and reliability inspection equipment based on actual field requirements and validate them in real operating environments.

Test equipment for reliability and defect inspection based on multi-SSD and PCI-E memory connections.

A temperature-controlled chamber system for evaluating sample reliability under changing temperature conditions, including heat resistance and thermal variation.

Relay hub equipment for power short-circuit reliability testing of USB memory devices.
Based on microprocessor-driven embedded design and software technologies, we develop precision measurement and automatic control systems,
and provide integrated solutions for real-time monitoring and remote control across wired and wireless network environments.





Overview and technical differentiation of the SMR inverter business
By applying the extreme-environment durability of submarine power-control technology to the nuclear field, we develop and supply dedicated inverter systems for small modular reactors (SMRs).
Through high-voltage stack compatibility and grid stabilization capabilities, we aim to secure differentiated technical positioning in the rapidly growing global SMR market.
Market opportunity analysis and partnership strategy for SMR inverters
The SMR market is growing rapidly alongside the global shift toward carbon neutrality, expanded distributed power systems, and stronger energy security. Based on its extreme-environment power-control technology, THEONE is focusing on participation in early-stage projects and on building initial reference cases.
More important than entering alone is building technical cooperation with leading global SMR companies and becoming part of their supply chains. A realistic path is to participate in domestic and international projects, accumulate certification and standards-response experience, and then expand step by step.
Participate in domestic SMR projects and align with innovative SMR technology development programs
Secure validated references and obtain global certification
Expand partnerships and supply-chain presence in global SMR projects
We aim to build technical cooperation with leading global SMR companies and establish a position within their supply chains.
We will continue SMR R&D while maintaining financial stability through existing cash-generating businesses such as submarine systems and ESS.
We distribute regional risk through participation in multinational projects and respond proactively to international standards and certification requirements.
Based on our defense certification experience and high-reliability design know-how, we reflect regulatory response systems from the early design stage.
