Keysight and Transphorm create power supply reference design that lowers product costs, speeds time to market

02/23/2021

Keysight Technologies, Inc., a leading technology company that helps enterprises, service providers and governments accelerate innovation to connect and secure the world, and Transphorm, Inc., a global supplier of high reliability, high performance gallium nitride (GaN) power conversion products, have announced the availability of a new power supply reference design that enables engineers to identify and correct design errors before building hardware, thereby lowering product costs and speeding time to market.

Switched-mode power supplies provide greater efficiency, increased power density and lower overall system costs when using GaN devices. However, GaN, a high switching speed, high performance wide bandgap semiconductor, can produce voltage spikes that result in detrimental radiated electromagnetic interference. As a result, optimized layout design and placement of components before building hardware is critical when using GaN.

The new power supply reference design, available with Keysight's PathWave Advanced Design System, is a virtual prototype based on Transphorm's 4 kW high efficiency single-phase AC-DC conversion evaluation board. It consists of the component and board models needed for engineers to visualize and optimize the time and frequency domains' behavior of voltages, currents and electromagnetic fields.
