At the heart of Silvretta — aCentauri Solar Racing‘s solar-powered challenger car entry in the grueling 3,022-kilometer Bridgestone World Solar Challenge (BWSC) across the Australian Outback — is a power electronics circuit using PowiGaN gallium nitride (GaN) technology from Power Integrations.

In 2023, while chasing solar-powered cars across the Australian Outback during the Bridgestone World Solar Challenge (BWSC), I found myself behind the wheel of a petrol-powered van. The irony wasn’t lost on anyone...

Designing a solar race car requires not only mechanical ingenuity but also highly efficient and compact electronics to manage power delivery across the vehicle. In this post, we explore the challenges of providing a DC-DC power supply for such a demanding application—and how Power Integrations rose to meet them.
