Using a High-Performance, Integrated AC Front End to Streamline Design and Reduce Time to Market

Among the many challenges of AC-DC converters and Power Factor Corrected (PFC) AC rectification is maintaining the desired performance across the worldwide mains, from low through high line, 85VRMS to 264VRMS. Maintaining high efficiency and power-factor usually forces design tradeoffs and operating compromises. The thermal system, as well as active and magnetic power components, has to be specified for worst-case scenarios. An alternative approach for the OEM is to “regionalize” the supply, but this also results in other design and supply chain drawbacks.

48 Vdc Distribution; a Safe, Practical and Efficient Solution for Equipment Racks

Vicor’s new AC Front End Module has an isolated, regulated output of 330 W at 48 Vdc. Its applications are many and varied, including powering rack-mounted equipment in telecommunications or data centres. However designers for such applications sometimes ask why the DC output has been set at 48 V rather than 12 V, or even 5 V?
