The Vox Power VCCS300 series of conduction-cooled ac/dc power supplies are 300-W units producing continuous output power in just a 2x4x1.61-in package. The all-in-one solution can be cooled using conduction, convection, or forced air cooling techniques. The VCCS300 series is a candidate for power solutions in applications where high efficiency, rugged reliability, silent operation, and […]
Single-phase
Reference design based on 4-kW high-efficiency single-phase ac-dc evaluation board
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, […]
Picking reliable power supplies
A few basic parameters can be useful for selecting power supplies that must work dependably in specific application scenarios. Alex Karapetian Acopian Power Supplies Electronic devices require a reliable source that can supply power at all times. But power supplies are available in a wide range of voltage and current ratings. Engineers tasked with selecting […]
