Nuremberg Germany: At the PCIM Power Electronics exhibition, Vicor announced additions to its IBC 050 and IBC 048 series of VI Brick intermediate bus converters. The new family already comprises more than 12 models in eighth- and quarter-brick formats delivering from 300 W up to 750 W.
Offering pin-to-pin, drop-in functional equivalence to industry-standard converters, the IBC 048 and IBC 050 enable designers to achieve increases in power density thanks not only to higher power ratings but also to printed circuit-board (PCB) space liberated by the reduced need for external passive components.
The latest model, the IB050Q096T70N1-00, is a high-power, 5:1 conversion ratio, open-frame drop-in replacement for industry-standard intermediate bus converters (see the figure). It operates from a wide input voltage range of 36 to 60 V at power levels of up to 750 W, with 2250-V dc isolation from input to output while achieving more than 98% peak efficiency.
The IB050Q096T70N1-00 also delivers an output bus voltage of 7 to 12 V, while other family members with 4:1 conversion output 8.7 to 15 V. The family includes standard 38- to 55-V input range converters (IBC 048) as well as the wide-input IBC 050 types.
The modules comply with ETSI EN300 132-2 for 48-V telecom applications, and their higher input-to-output isolation complies with IEEE 802.3 Power-over-Ethernet (PoE) standards. The IBC 048 and IBC 050 VI Brick bus converters also use Vicor’s Sine Amplitude Converter technology.
