Power supply designers, power electronics manufacturers, and R&D engineers developing AI data centers, telecommunications equipment, industrial systems, semiconductor manufacturing equipment, medical devices, test and measurement equipment, and other high-efficiency, high-power-density power conversion systems.

TriMagiC Converter™ (TMC) is primarily targeted at high-power power supply applications requiring compact size, high efficiency, and high power density. Currently, we are developing and evaluating isolated DC-DC converters in the 1.6 kW and 3.3 kW classes, targeting applications such as data centers, industrial equipment, and telecommunications systems where both high efficiency and compact design are essential.

In particular, power supplies for AI data centers are facing increasing demands for higher output power, higher-density packaging, and improved thermal performance. By integrating the functions of the main transformer and output smoothing inductor required in conventional PSFB converters, TMC significantly reduces the number and volume of magnetic components, contributing to smaller and lower-loss power supplies.

TriMagiC Converter™ employs a unique ON-ON & ON-OFF operating topology while maintaining the same control method as conventional phase-shift full-bridge converters. The technology reduces magnetic component volume to approximately one-third and power supply size to approximately two-thirds of conventional designs. It also enables output capacitor reduction, lower magnetic losses, and high-efficiency ZVS operation. High power density can be achieved using standard silicon MOSFETs without requiring SiC or GaN devices. Joint development and prototype evaluations are currently underway with research institutes and power supply manufacturers.
