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.
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 (more info).
