A discussion with global engineering and procurement teams

HUIWEI GROUP / 02

A focused path from devices to systems

Huiwei connects SiC device selection with the power architectures used in AI infrastructure.

Power semiconductors

650V, 1200V and 1700V SiC MOSFETs; 650V and 3300V SiC diodes

Server power

Device evaluation for PFC and high density power conversion

System concepts

800VDC distribution and 13.8kV to 800VDC solid state transformer research

HUIWEI GROUP / 03

Find a device for the design stage

Public datasheets provide starting points for electrical screening. Final selection requires application testing.

650V

SiC diodes and MOSFETs for front end and PFC evaluation

1200V

MOSFET options for higher voltage conversion stages

1700V

MOSFET option for industrial and high voltage evaluation

3300V

90A SiC Schottky diode for high voltage module evaluation

Where Huiwei can help

Start with a specific operating point, then compare device options and validation needs.

01

Share topology, bus voltage, switching frequency and thermal limits

02

Shortlist available Huiwei datasheets and package options

03

Define samples, bench tests and qualification requirements

04

Discuss system integration with the customer and qualified partners

HUIWEI GROUP / 05

AI server power opportunities

SiC devices can be evaluated across existing server power designs and future 800VDC architectures.

Today

PFC and conversion stage device evaluation in ATX and CRPS power supplies

Next

6.4kW and 7.4kW class CRPS design discussions

Exploration

800VDC distribution, backup power interfaces and rack integration

HUIWEI GROUP / 06

An architecture for engineering dialogue

A reference concept links medium voltage input, conversion and rack power. Design and safety depend on the deployment.

13.8kVAC input → SiC SST concept → 800VDC distribution
800VDC distribution → rack conversion and BBU interface → AI compute racks
AI NIC / DPU is a separate networking workstream.

HUIWEI GROUP / 07

Two operating centers; wider ambitions

Current operations are based in Taiwan and Shanghai.

Taiwan

Huiwei Technology: group headquarters, SiC and AI server power work

Shanghai

Shanghai Huiweida Semiconductor: semiconductor and China market work

Tokyo

Company formation and related review in progress

Phoenix

U.S. operation under planning
