VI Chip Bus Converter Modules Slide 2

Both commercial and MIL-COTS versions of the VI Chip BCM™ modules, and the VI BRICK Intermediate Bus Converters are fixed ratio, isolated DC Sine Amplitude Converters developed from a patented transformer-based, series resonant topology. The Sine Amplitude Converter™ powertrain is fast, flexible and efficient and is the driving force behind the high performance power conversion of Vicor’s bus converters. The sinusoidal current flow within the converter enables key performance benefits including: the converter can easily operate at several MHz; all of the silicon switch transitions occur at zero voltage and zero current; the sine amplitude converter always operates at the resonant frequency; the filter design is easy and cost-effective and can be sized for a switching frequency greater than 1 MHz; the extremely narrow EMI spectrum presents greatly reduced harmonic current; and derating requirements for all components are reduced.
