Vicor Corporation Expands Its Product Line With Factored Power Architecture

The VI BRICK® AC Input Stage Module supplies an isolated 330W, 48V power factor corrected output in the size of a business card

 

Vicor™ today announced the expansion of its Factorized Power Architecture® product line by introducing new higher power versions of its VI Chip® PRM® Non-Isolated Voltage Regulators. Delivering up to 500W of power and twice the power density of previous generation modules, these new PRM products consolidate Vicor's leadership as a provider of next-level power solutions for demanding applications in industry, power centers, data and telecommunications. Vicor's Factorized Power Architecture (FPA®) separates, or 'factors', voltage regulation and transformation functions into flexible, high-performance building blocks. PRM modules accept an unregulated input voltage and generate a regulated output; VI Chip VTM® Current Multipliers provide current and voltage isolation and transformation. Together, they offer the highest levels of density and efficiency on the market for converting an unregulated 48V bus to the low voltages – starting at 0,5 VDC – required by today's electronics. The flexibility of the architecture and the benefits in terms of performance of FPA allow you to create distributed power and conversion systems in less space, with minimal complexity and significantly lower power losses than with conventional conversion architectures. Incorporating an advanced version of Vicor's high frequency zero voltage switching (ZVS) buck-boost technology, the new PRM modules can supply up to 500W with greater than 97% efficiency and with unprecedented power densities of up to 1700 W/cubic inch (103 W/cm3). Models come in full-chip and half-chip packages, with input voltage ranges of 36-75V and 38-55V, and can generate an isolated 0,5V to 55VDC output when used in conjunction with multipliers VTM current. Customers can configure operation in any of three selectable regulation modes – adaptive loop, local loop and remote sensing operation – to ensure voltage accuracy at the application load point.
