Introduction
---------------------------------------------------------------
We obtained Segotep’s newly released 3200W Titanium-rated SiC digital power supply. This unit follows the standard CRPS form factor and adopts a fully digital control solution from Texas Instruments. It integrates two DSP chips—one dedicated to interleaved totem-pole PFC control and the other for full-bridge LLC control. The model designation is CRPS3200W-12V, and it supports a wide input voltage range.

Segotep is positioning itself in the high-end CRPS market by emphasizing modularity and standardization to achieve broad compatibility. The design consists of eight PCB modules, scalable up to 5.5 kW at 54 V output (including DSP algorithm optimization). Each module is manufactured using a fully automated SMT process, with a heatsink-free and pre-processing-free design. The DSP-based modular architecture allows minor upgrades to support higher power ratings and even three-phase input configurations in the future. This approach enables rapid product development based on a unified technical platform, minimizing validation and investment time while allowing customization of specific modules to meet individual client requirements.

The power supply delivers a rated output of 12.2 V at 262.3 A, with an auxiliary standby output of 12 V at 3 A. It features a long rectangular metal chassis, and the totem-pole PFC stage employs Infineon silicon carbide MOSFETs. The following teardown provides an in-depth look at the internal layout, design approach, and component selection.
