Amperesand is a Singapore-based startup developing a medium-voltage solid-state transformer.

Amperesand is a Singapore-based startup developing a medium-voltage solid-state transformer. They were spun out of [[Nanyang Technological University]] (NTU) through a pilot programme between [[Nanyang Technological University|NTU]], the [[National University of Singapore]], and [[Temasek]].

Amperesand infrastructure systems are built with solid-state transformer (SST) modules. Each module contains silicon carbide (SiC) devices and proprietary high-frequency transformers that are significantly more efficient, flexible, and resilient than traditional transformers. This modularity also allows scaling for various applications.
