Transphorm’s customer base includes product manufacturers unsatisfied with the status quo. Companies on the bleeding edge of innovation that strive to break their own power system performance records, raising the bar industry-wide. Gallium nitride power transistors are proving to be their disruptive technology of choice.
High-end PC Gaming power supply users demand high wattage output, low audible noise, ripple suppression, good thermal efficiency, and long warranties. CORSAIR’s GaN-based AX1600i PSU outperformed its award-winning predecessor. The PSU’s marked performance also earned it a new customer base: cryptocurrency and Artificial Intelligence (AI).
Seasonic relies on a high efficiency platform to serve as the foundation for a broad range of power products: from battery chargers to multi-market catalog power supply units. Seasonic’s new 1600 W platform is the company’s most efficient PFC platform to date, with a 20% power density increase.
The bridgeless totem-pole PFC is often promoted as the ideal topology to optimize all inherent GaN benefits. However, Delta Electronics deploys GaN in a CCM Boost Converter to maximize a key benefit—circuit size reduction. With a 25% smaller system, the ODM’s latest 800 W server PSU maintains an 80Plus Platinum rating within a standard form factor.
High quality, high reliability GaN in standard TO-XXX packages.
Transphorm’s GaN FETs switch up to 4x faster than Silicon solutions. Further, unlike Si MOSFETs, the GaN transistors are inherently bi-directional and optimized in a bridgeless totem-pole power factor correction design.
High-voltage GaN technology benefits numerous markets that require reliable higher efficiency, higher performance power conversion. The highest adoption rates are projected for the following application areas:
Increases clean power output in standardized server and telecom form factors.
Allows for significantly smaller, lighter PV inverter and residential applications.
Enables reduction of total solution complexity while improving precision.
Generates longer distance per charge with a lower overall system cost.
