V·I chip components increase efficiency and power density
22 August 2007
Power Electronics / Power Management
Vicor has available a full family of V·I chip components, enabling complete power systems using factorised power architecture (FPA). FPA separates or 'factorises' regulation and voltage transformation functions into flexible, high-performance building blocks. V·I chip components are high-density (up to 73 W/cm³), high-efficiency (up to 97%), high-speed power conversion modules.
The PRM (non-isolated regulator) and VTM (current multiplier) components deliver the most efficient 48 V direct-to-load power conversion system in mass production today, according to Vicor. For low voltage/high current requirements (eg, microprocessors), the VTM module enables 14,1 A/cm² point of load (POL) density. FPA allows the PRM module to be deployed remotely, providing greater design flexibility and a 95% reduction in distribution loss.
As energy prices increase, the electricity bill for a data centre is now 50% of the annual operating cost - growing to more than the initial hardware investment - and it takes 2,6 W to drive 1 W of computing power in a typical system. A data centre using an FPA solution could save $30 per processor, per year in energy costs. At the same time, the power solution with V*#183;I chip modules is 45% smaller, enabling further increases in computing rack density.
Vicor's PRM and VTM modules cover a wide range of input and output voltages at power densities up to 73 W/cm³ or 100 A per module. FPA solutions are available to meet the advanced requirements of telecom/server (processor and memory power supply), test equipment, RF amplifiers, power supplies, and many other applications.
Vicor's intermediate bus converters, the 48 V BCM modules are available with output voltages of 1,5 Vout to 48 Vout and up to 300 W and are suitable for telecom/server, base stations, WiFi, data/voice, VoIP, and PoE, as well as solid-state LED lighting, lasers, and broadcast equipment. In addition, Vicor's high-voltage (350-380 Vin) BCM converters provide efficient high-voltage distribution and post-PFC high voltage DC-DC conversion to non-isolated POL converters in telecom and high-end server systems.
