PSA unboXed and Amperesand, a grid infrastructure solutions supplier, have begun a collaborative experiment to test a solid-state transformer (SST) technology in its Singapore facility.
Amperesand’s SST technology reportedly offers safe and efficient high-power charging for PSA’s electric fleet, with integrated energy monitoring and management capabilities.
SST solutions use silicon carbide (SiC) devices and patented high-frequency modules to improve power efficiency and minimise grid strain in a small form factor.
Amperesand’s technology enables efficient energy routing and innovative applications like vehicle-to-grid.

The modular and expandable architecture allows PSA to easily manage its electric car charging facilities, distributing electricity efficiently throughout the facility’s high-capacity dispensers.
The cooperation will begin with a one-year Proof of Value (PoV) starting in mid-2025.
The PoV aims to collect data on the functionality, performance, and cost of Amperesand’s SST in PSA’s fleet charging application, with the potential to enable more port electrification.

Nelson Quek, Regional CEO Southeast Asia, PSA International, said: “By evaluating solid-state transformer technology at PSA Singapore, we aim to gain strategic insights that could inform our approach to sustainable electrification and operational resilience in the future.”
Alvin Foo, Head of Technology and Sustainability Solutions, PSA Singapore & Head of PSA
unboXed, stated: “Following our preliminary assessment, PSA finds Amperesand’s SST technology
promising and I look forward to the positive outcomes from the PoV trial as it has the potential to
enhance our efforts in sustainable electrification at the port.”
