Wise-integration presents OBC demo board
Wise-integration, a pioneer in digital control for GaN and GaN IC-based power supplies, will break new ground at PCIM Europe 2025, May 6–8 in Nuremberg, Germany.
In collaboration with Savoy International Group, the company will debut its digital controller with a SiC power demonstrator model, underscoring its expansion into complementary wide-bandgap (WBG) technologies and showcasing its WiseWare digital controller’s universality and adaptability across those technologies.
This marks a new market entry for Wise-integration—in particular, targeting SiC-based high-voltage applications in automotive and industrial sectors—while reinforcing that WiseWare can serve as a common digital intelligence layer regardless of the underlying semiconductor material.
The WiseWare 1 OBC SIC 7kW power demonstrator model builds on the company’s core expertise in GaN-based systems and digital control ICs, reinforcing its commitment to advancing the full spectrum of power semiconductor technologies. This cross-compatible, digital control solution for both GaN and SiC, enables flexible, efficient, and intelligent power systems across multiple WBG platforms.
“This demonstration of a SiC onboard charger (OBC) marks an important step in Wise-integration’s journey toward the automotive market,” said CEO Thierry Bouchet. “By showing that WiseWare can reliably control high-voltage, high-power systems in an EV-relevant application, we’re validating our digital control platform as a strong candidate for next-generation onboard chargers. It’s a first step toward demonstrating that our technology is scalable, adaptable, and aligned with the needs of future EV platforms.”
The demonstrator is a prototype product for the company’s partner, Savoy International Group, a Tier 1 automotive supplier, whose e-mobility division collaborated with Wise-integration on a GaN charger embedded in e-bike batteries in 2023.
“This prototype has been developed specifically to support the electrification of Savoy’s innovative, light electric vehicles under the KILOW brand, as well as their broader ambition to promote fun, accessible, and sustainable mobility solutions,” Bouchet explained.
“Our previous collaboration with Wise-integration on the embedded GaN charger for our e-bike battery met all of our expectations for performance and helps us differentiate KILOW in a crowded field,” said Émile Allamand, CEO of Savoy Group. “The SiC onboard charger will enable us to diversify our EV offerings with a light, four-wheel vehicle under our KILOW brand.”
