Visic raises $10m for GaN development

Visic evaluation board for GaN transistors

Gallium nitride (GaN) semiconductor firm Visic Technologies has closed $10m in a series D round of financing lead by a private investor. Its technology is primarily used in electric vehicles.

The electrification of automotive vehicles has been growing at an unprecedented pace in the recent past and will continue to grow for the foreseeable future. GaN power devices get the increased performance out of high-power, high-voltage power conversion systems inside hybrid and electric vehicles.

The improved size, weight, efficiency and heat management of the on-board charger and the DC-DC converter, designed with GaN power devices, all contribute to faster charging and longer driving range.

High performance power supplies for telecoms systems and data centres are also using GaN power devices to reach new levels of density and efficiency, bringing down the electricity costs of the operators significantly.

“GaN technology opens a new space in power electronics, from shifting the performance envelope up to the point of new topologies development,” said Ivan Feno, principal power design engineer from Bel Power. “We are delighted to see Visic offering specifically rugged GaN devices with negligible fast transient dynamic RDSon.”

The insulated thermal pad enables the increase of the power stage reliability and density. Ultimately, he said, 1.2kV rated GaN devices might be an attractive alternative in the 1.2kV segment dominated by SiC technology today.

Visic’s technology in combination with R&D designs by large players in the power electronics industry, made it possible to close this round of funding on favourable terms.

“We are very excited by the level of enthusiasm of Visic’s investor, who believes in the enormous potential of Visic’s GaN products,” said Tamara Baksht, Visic Technologies’ founder and CEO. “With the new funding, we can expand our portfolio further to address more market segments. Furthermore, we will increase our technical support team to assist our growing worldwide customer base.”

Based in Nes Ziona, Israel, Visic Technologies was established in 2010 by experts in GaN technology to develop and sell GaN-based power conversion products. Visic has developed, and is bringing to market, high-power GaN-based transistors and modules.
