Energy Storage

As the global transition to clean energy accelerates, Battery Energy Storage Systems (BESS) require unprecedented levels of efficiency, grid stability, and thermal management. Quest Semi meets this challenge head-on by utilizing high-voltage Silicon Carbide (SiC) semiconductors—including our industry-leading 5kV and 10kV SiC Schottky diodes and MOSFETs. By operating at higher DC bus voltages, these advanced wide-bandgap (WBG) discrete components drastically reduce current losses, eliminate traditional recovery bottlenecks, and minimize thermal dissipation by up to 75% compared to legacy silicon.

This enables bidirectional power converters to achieve rapid switching speeds and higher power densities while handling massive current transients. Ultimately, integrating Quest Semi’s rugged, fast-switching technology into utility-scale storage designs ensures superior grid stabilization, minimizes power failures, and creates a more reliable framework for renewable energy deployment.
