## Summary

Raised $80M Series A (Nov 2025). Silicon-carbide SST spun out of Nanyang Technological University. Backed by Temasek and TDK Ventures. Targeting 185 GW data center capacity by 2028.

## Company Overview

Amperesand is a solid-state transformer company spun out of Nanyang Technological University (NTU) in Singapore, developing silicon-carbide based SSTs for data centers and grid applications. The company raised $80 million in Series A financing in November 2025, backed by Temasek (Singapore's sovereign wealth fund) and TDK Ventures, positioning itself as the Asia-Pacific entrant in the solid-state transformer category that has attracted significant 2026 investment globally.

Silicon-carbide (SiC) is Amperesand's chosen semiconductor material — a compound semiconductor that operates at higher temperatures and switching frequencies than silicon, enabling more compact and efficient power conversion circuits. SiC-based power devices have already proven themselves in EV inverters (Tesla, BYD use SiC in their drivetrain inverters) and Amperesand is applying the same material advantages to grid-scale transformer replacement.

The data center targeting is deliberate: AI-driven data center construction is driving unprecedented demand for power infrastructure upgrades, and the traditional grid transformers serving data centers are increasingly inadequate for the power quality, density, and bidirectional flow requirements of modern hyperscale facilities. Amperesand's SSTs can manage complex power flows from on-site solar, backup generators, grid connections, and UPS systems in a single integrated device rather than the multiple discrete systems current data centers require.

## Frequently Asked Questions

### What does Amperesand make?
Silicon-carbide solid-state transformers for data centers and grid applications — SiC enables more compact and efficient power conversion than silicon, same material proven in EV inverters.

### How much has Amperesand raised?
$80M Series A in November 2025, backed by Temasek and TDK Ventures. NTU Singapore spinout.

### Why target data centers with SSTs?
AI data center construction requires power infrastructure managing solar, generators, grid connections, and UPS in one device. Traditional transformers can't handle complex bidirectional flows.

### What is SiC's advantage over silicon?
Silicon-carbide operates at higher temperatures and switching frequencies — enabling more compact, efficient transformers. Already proven in EV drivetrain inverters at Tesla and BYD.

### What problem does Amperesand solve with silicon carbide transformers?
Traditional copper-wound transformers are bulky, slow to install, and cannot efficiently handle bidirectional power flow from solar, batteries, and EV chargers. Amperesand's silicon carbide solid-state transformers are compact, digitally controllable, and natively handle AC/DC conversion — enabling smarter, faster grid connections for the energy transition.

### Who are Amperesand's target customers?
Amperesand targets utilities deploying distributed energy resources, EV fleet charging depot operators, renewable energy developers connecting solar and storage to the grid, and data center developers requiring high-density power conversion infrastructure.

### What advantage does silicon carbide (SiC) have over traditional transformer materials?
SiC power semiconductors switch at much higher frequencies than silicon-based devices, enabling transformers that are 5-10x smaller and lighter than equivalent copper-core designs. SiC also operates at higher voltages with lower switching losses, improving overall system efficiency.

### What is Amperesand's stage of development?
Amperesand is at the pilot/commercial demonstration stage, deploying its solid-state transformer platforms in controlled utility and commercial settings to validate performance, reliability, and total cost of ownership ahead of broader market entry.
