A new power supply reference design 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, […]

Test instruments help tame power factor and signal integrity
by Simran Nanda, Keysight Technologies Harmonic analysis helps design electronics that will behave well on the power grid. Electronics that include switch-mode power supplies (SMPSs) and VFDs depend on non-linear components to minimize size and cost. This approach, however, forces designers to note the impact non-linear current flows have on the signal integrity of the input […]
