PSDtv – GaN Systems Shows Significant Size and Power Density Gains

G-Philos 700W GaN-based ESS is 30% smaller, 25% less power consumption than silicon version

GaN Systems President Girvan Patterson describes a 1 kV energy storage system (ESS) from Korean-based customer G-Philos that stores solar-generated power and returns unconsumed power to the grid. The GaN-based design uses both 650 V and 100 V transistors, is up to 80% smaller and considerably lighter than its silicon-based progenitor. The ESS is cooled passively, requiring no fans, which further enhances the system’s reliability.

This is yet another example of a customer product in production that uses GaN transistors to outperform silicon-based solutions.
