Atom Achieves Over 97% Efficiency with Next-Generation Matrix Transformer, Validated by Konkuk University

On April 23, Atom officially announced that the performance of its next-generation power technology has been validated through the "Matrix Transformer Verification Report" issued by the Power Electronics Laboratory at Konkuk University.

In this verification, Atom's next-generation transformer achieved an efficiency of 97.071% under a 3.2kW load condition at the early stage of research and development. This result is evaluated as a significant reduction in energy loss during the power conversion process. Additionally, under input conditions of 400V and 3.2kW, the temperature deviation between parts was within 5 degrees Celsius, and the efficiency deviation was at the level of 0.73%.

The company explained that this achievement goes beyond the limitations of conventional circuit-based products. In particular, Atom stated that it increased technological completeness by successfully maintaining core heating at a stable level of around 45 degrees Celsius even under high-output conditions.

Competitiveness in manufacturing was also highlighted. Atom achieved high efficiency, low heat generation, and cost reduction simultaneously by applying its own method without using expensive multilayer boards (MLB). The company announced that, as a result, it has secured cost competitiveness approximately 25% to 30% lower than that of competitors.

Currently, Atom is also in the final stages of developing its "Composite Matrix OBC Molding Transformer." This is an advanced product based on the composite planar OBC transformer applied in the Tesla Cybertruck, further enhanced with Atom's proprietary technology. The company expects positive results in the upcoming second test of the 800V, 11kW-class model scheduled for the end of April.

Atom especially emphasized differentiation by integrating the same functions into a single transformer, in contrast to Tesla, which applied four MLB planar transformers for the 11kW standard in the Cybertruck.

Meanwhile, Atom recently formed a partnership by being officially registered as a vendor for Hyundai Mobis. The company explained that this means its planar transformer technology has passed the strict reliability verification required by global automakers and has been recognized as a next-generation standard technology.
