# India Launches National Initiative for Indigenous Silicon Carbide (SiC) Power Modules in Ultra-High Voltage VSC-HVDC Transmission

> To end reliance on imported semiconductor valves for mega renewable transmission corridors, India’s Ministry of Power and Ministry of Electronics and IT (MeitY) have launched a nationwide mission to develop indigenous 3.3 kV to 6.5 kV Silicon Carbide (SiC) MOSFET power modules for VSC-HVDC converter stations.

## Overcoming Global Converter Valve Supply Bottlenecks

With transmission utilities like Power Grid Corporation of India deploying gigawatt-scale corridors—including the 800 kV Barmer-to-Maharashtra renewable link—global converter valve lead times have stretched past 36 months.

The joint initiative funds domestic packaging and fabrication of SiC power electronic modules that deliver 70% lower switching losses and operate at junction temperatures up to 175°C, slashing converter station cooling requirements and footprint.

## Interoperability with Heavy HVDC Converter Transformers

The consortium, bringing together central engineering institutes and industrial manufacturers like BHEL, will standardize high-speed gate driver interfaces and transient voltage suppression across ±500 kV and ±800 kV converter transformers.

Pilot field trials on a 400 kV static synchronous compensator (STATCOM) are slated for late 2027, paving the way for commercial HVDC adoption by 2029.
