Power modules serve test applications
Staff -- Test & Measurement World, 3/1/2004
Vicor's family of 48-V Intermediate Bus Converter Modules (IBCs) serve test-system and other applications requiring power distribution. Offered in standard 1/4-brick format and operating from 38- to 55-VDC inputs, the IBC family consists of nine fixed-ratio standard models with nominal outputs from 3 to 48 VDC (3, 4, 6, 8, 9.6, 12, 16, 24, and 48 V), delivering up to 100 A or 600 W. Efficiency of the IBCs ranges from 95% at 3 V to better than 97% at 48 V. Full power is available with only 200-LFM (linear feet per minute), 55°C air cooling without a heat sink.
The products' efficiency and transient performance result from the use of Vicor's proprietary Sine Amplitude Converter (SAC) technology, which provides zero-current and zero-voltage switching at a fixed, multi-megahertz rate. SACs also provide exceptionally low input and output noise, reducing or even eliminating costly and bulky filters.
