VisIC Technologies – introduction

VisIC Technologies has a decade of experience in creating, developing, and advancing concepts based on cutting-edge Gallium Nitride-on-silicon technology. We develop solutions that help reduce energy waste in power conversion systems, with a focus on battery electric vehicles (BEV). Our patented D3GaN technology – Direct Drive D-mode GaN – addresses the automotive industry’s cost, supply, sustainability, reliability, quality, and performance needs.

With our D3GaN technology, the CO2 footprint can be reduced by over 1.4t relative to silicon solutions, during a lifecycle of a BEV, by improving the efficiency of the inverter. The technology is designed for the highest reliability as it uses the widest gate voltage, which can withstand the harsh gate voltage stress induced by the inductive design of the inverter application. With this solution, BEV can save 50% on power losses over the driving cycle of the electric car, thus reducing battery cost and increasing driving range and performance. This solution also reduces the cooling system requirements and the size of the BEV inverter.

The D3GaN devices support 400-volt and 800-volt bus systems, commonly used in today’s electronic car models. The D3GaN technology also allows easy and simple paralleling, a critical feature for an inverter, and features state-of-art packaging for reliable power dissipation.

VisIC Technologies has produced the first GaN-based transistors used in automotive inverters. By utilizing the GaN on Silicon technology, we address the supply chain concern as we are using existing semiconductor high-volume production lines, which can scale from 150 to 200mm and further to 300mm wafer size, of Silicon’s existing cost base material.
