Keysight Technologies and Transphorm 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 (download user guide here), 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.
"The need for switch-mode power supplies is driving rapid adoption of wide bandgap semiconductors," said Tom Lillig, general manager of Keysight's PathWave Software Solutions division. "The new reference design of Transphorm's high voltage GaN solution will speed time to market of this technology, which is changing how the world powers electronic products.”
