Transphorm, Inc., the global provider of GaN power semiconductors, announced the release of a new 300-W dc-to-dc GaN reference design for two and three-wheeled electric vehicle (EV) battery chargers.
The TDDCDC-TPH-IN-BI-LLC-300W-RD design uses TP65H150G4PS 150 mOhm SuperGaN FETs in a reliable TO-220 package to power a high-performing, high-efficiency energy harvesting, and distribution battery charging system.
The new board notably demonstrates one of the most anticipated value propositions of a GaN power supply: bidirectionality. This capability indicates that a single power system can deliver power in two directions from input (ac) to output (dc) and output (dc) to input (ac) depending on system needs, with GaN enabling energy efficiency in both conversions.
Bidirectionality is a core capability required to advance V2X (vehicle-to-everything) infrastructure for e-mobility applications that comprise V2L (vehicle-to-load), V2H (vehicle-to-house), and V2G (vehicle-to-grid) scenarios, which represent a projected overall V2X system market size ranging from a conservative nine billion to an aggressive 70 billion USD by 2030.
In EV systems, renewable energy systems, and other applications within the V2X model, design and performance flexibility will be critical to innovation and wider deployment. The high power density and bidirectionality is a key enabler for this area. The V2X applications are prime use cases that can leverage all the SuperGaN technology’s superior value proposition. This new reference design is an exciting example of what’s possible in a future enabled by SuperGaN technology.
