Insights
The introduction of Transphorm's new 300 W DC-to-DC GaN reference design is a significant development in the field of electronic mobility and energy solutions. The use of Gallium Nitride (GaN) semiconductors, specifically the TP65H150G4PS 150 mOhm SuperGaN® FETs, underscores the ongoing shift towards higher efficiency and smaller form factor power systems.
Bidirectional power conversion is a standout feature, enabling power to flow both ways— from AC to DC and back, depending on system requirements. This is pivotal in advancing V2X (vehicle-to-everything) infrastructure, including V2L (vehicle-to-load), V2H (vehicle-to-house) and V2G (vehicle-to-grid) systems. The power density and efficiency, marked at
For investors, the benefits are clear. GaN technology's ability to reduce size and cost while improving efficiency positions it favorably against traditional silicon-based technologies. This could potentially lead to increased adoption in various high-power applications, ranging from electric vehicle chargers to renewable energy systems.
The market for V2X systems is projected to grow significantly, with estimates ranging from
From a market perspective, the ability to simplify and speed up power system development — thanks to its fully analog implementation — can attract a broad user base. This is important for sectors like e-mobility and renewable energy, where quick time-to-market can provide a competitive edge.
Overall, this development is positive for Transphorm, potentially enabling them to capture a larger share of the growing V2X and high-power application markets.
Financially, the launch of this new GaN reference design could drive significant revenue growth for Transphorm. The high efficiency and bidirectional capabilities of the product are likely to attract contracts from OEMs and system integrators in the EV and renewable energy sectors. Given the projected market size for V2X systems, even a small market penetration could translate into substantial revenue.
Moreover, the innovation aligns with the broader industry trend towards more efficient and compact power systems, which could favorably impact the company's stock performance in the medium to long term. However, potential investors should monitor how quickly and widely this technology is adopted, as well as any competing technologies that might emerge.
300 W DC-to-DC Battery Charger Board Showcases Key Capability of GaN Technology Necessary to Advance E-Mobility Applications
“The first value proposition of GaN in high power applications was realized by the highly efficient operation of the bridgeless totem-pole power factor correction circuit. This subsequently led to the next level of benefits across a variety of topologies, including overall smaller and lower-cost power systems across the full power conversion spectrum, from 30 watts to over 10 kilowatts,” said Primit Parikh, President and CEO, Transphorm. “Continuing the leadership of Transphorm GaN in higher power applications, we have now demonstrated bidirectional power conversion that can be used by vehicle on-board chargers for e-mobility, renewable energy and backup power systems, and other power supply applications requiring highly integrated, interchangeable input and output terminals.”
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
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 truly 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.
