TECHNOLOGY & PRODUCTS
The conversion technology built for EV wireless charging branched in four directions. Robotics is the same technology made smaller, the data centre is the same technology pushed to higher density, and renewable energy is the same technology scaled up. Monitoring is the layer that attaches to all of them.
It began with a single receive pad and grew into vehicle-mounted parts, transmitters, and a combined wired-and-wireless charging platform. Every technology in the company came out of this segment.

Read more →As the power drawn by a single AI server rose, the power supply became the bottleneck. Starting with the server PSU, we are taking on the power path inside the rack one stage at a time — including backup and buffering.
Read more →The bidirectional AC/DC design built for wireless charging scales up to grid-tied capacity. It starts residential and climbs to commercial and utility scale on the same structure.
Read more →As conversion equipment multiplies, something has to read and control it. We start at the equipment edge with RTUs and gateways, and move up to plant-level supervision and control.

Sending power across the air gap from a pad in the ground to a pad under a vehicle, and stepping grid voltage down to what a processor consumes inside a data centre, are the same problem. Switch at high frequency, cut the losses with resonance, carry it through magnetics.
POWER RANGE
A different power level asks for a different design. We develop in three bands and carry what we prove in one band across to the others.
We demonstrated micro-EV wireless charging on public roads in the Gyeongbuk regulatory free zone. Since 2026 we have been developing receive modules for outdoor mobile robots under a public project and a commercial contract at the same time.
We hold physical receive pads with integrated rectifiers built to SAE J2954. The fast wireless transmitter is being developed with operational compatibility secured alongside it.
We are building a wireless charging reference model that scales by paralleling unit modules, together with a real-environment testbed. The grid-tied PCS and AI server power cover the feed path from grid to load.

CAPABILITY
Running the 2024 performance evaluation of 40kW power-bank conversion components as lead institution gave us an evaluation framework alongside the ability to build the components.
We hold power conversion test equipment including bidirectional power supplies, and are adding equipment in step with the fast transmitter development.
We use the RAPA IoT technology support centre and the Kyungpook National University testbed as staged demonstration environments, and have carried work through vehicle modification, mounting and on-road operation.
EMC and EMF certification sit within our own scope of work. Ingress protection is designed to the required class, from outdoor robot use to vehicle mounting.
We design against SAE J2954, ISO 15118-20 and OCPP 2.0.1, and take part in international standardisation activity in wireless power transfer.
ROADMAP
Technical directions we are preparing at the research and development stage.
A multi-stage structure that steps grid power down to the point directly ahead of the compute silicon. It is the next step beyond the AI server power module now in development.
Devices that answer the transient load swings and outages of an AI data centre. High-density conversion and bidirectional control apply here directly.
Load-side conversion for high-efficiency solid-state transformers connected to microgrids, together with predictive maintenance.
Adding IEC-standard monitoring and security to conversion equipment already installed, through an add-on module.
