About MVSST Power

A SiC Power Electronics & SST Engineering Platform

We supply medium-voltage SiC power modules, components and custom solid-state transformer solutions — engineered with a specialized manufacturer and delivered with one accountable export partner.

Home/About Us
Who We Are

Xuzhou Weike Mining Technology Co., Ltd.

MVSST Power is the export platform of Xuzhou Weike Mining Technology Co., Ltd., headquartered in Xuzhou, Jiangsu, China. We focus on bringing medium-voltage power-electronics technology to overseas customers — supplying MV SiC power modules, SiC power components and power devices for SST projects and MV converters.

Beyond components, we provide custom engineering solutions: from SiC device selection and topology consultation to complete solid-state transformer systems developed per project. Full SST systems are offered as project-oriented custom development, not off-the-shelf stock products.

We act as the single accountable point of contact for international customers — one team that understands your application, configures the right components and subsystems, manages export documentation and supports you through prototyping, testing and deployment.

Engineering Capabilities

What We Can Engineer for You

Topology & System Design

MVAC/DC converter topologies, power-cell architecture, redundancy and protection coordination for your application and grid code.

High-Frequency Magnetics

HF transformers and inductors for 10–100 kHz operation — the size and weight breakthrough in SST systems.

Control & Communication

Digital control, fault handling and full IEC 61850 / Modbus / DNP3 integration with your SCADA or facility BMS.

Thermal & Mechanical

Liquid and forced-air cooling design, thermal cycling validation and enclosure engineering for site conditions.

EMC & Standards

Design against IEC 60076, IEC 61850, IEEE 1547, IEC 61000 / IEEE 519 with compliance documentation per project.

Export & Documentation

Full technical dossier, factory test reports, export packaging and shipping terms managed end to end.

Testing Capabilities

Tested, Documented, Verifiable

Every component and system ships with test evidence. For SST and MV projects, we run a staged test program:

  • Factory Acceptance Tests (FAT) — performance verification against the agreed specification
  • Type tests — dielectric, thermal, functional and EMC testing per the applicable standard
  • Thermal cycling & burn-in — reliability validation for power modules and complete units
  • Grid-simulation tests — LVRT/HVRT, reactive and fault behavior on test rigs
  • On-site commissioning — installation supervision, test reports and operator training

Test reports are included in the delivery dossier — your engineers can verify what you are buying.
