High-density DC-DC bricks

27 August 2014 Power Electronics / Power Management

Vicor has débuted a new series of DC-DC bricks in the form of the HD Brick Series of isolated converters, which retains the fundamental design attributes of conventional bricks while combining up to 51% greater power density with efficiency levels up to 94%.

The devices enable system designers to harness more power in less space than with Vicor’s earlier generation Maxi, Mini and Micro DC-DC converters. The first two standard offerings in the new family are a 320 W HD brick with nominal 28 Vin (16 –50 V input range) and 28 Vout, in a 48,6 x 46,5 x 16 mm package; and a 400 W HD brick with nominal 300 Vin (180 – 420 V input range) and 12 Vout, in a 57 x 46,5 x 16 mm package.

These converters are available in flanged and flangeless versions, can operate in harsh environments, and support three temperature grades, including operation down to -55°C. They can be deployed in combination with Vicor’s ZVS buck regulators and VI Chip power components to power the point-of-load portion of a power system.
