High-boost Harmonic Attenuator Module

October 7, 2005


Vicor’s high-boost VI-HAM is a universal AC input, PFC front-end module that has been optimised for use with Vicor’s V375 series of DC-DC converters. A single high-boost VI-HAM may be used with any combination of V375 series DC-DC converters up to 600 Watts, resulting in a power conversion system with high power density, few components, and low cost

Parallelable versions of the VI-HAM are available for applications requiring over 600 Watts of output power. In addition, the high-boost VI-HAM is fully compatible with Vicor’s VI-26x and VI-J6x series DC-DC converters, giving designers the freedom to choose from the industry’s broadest selection of DC-DC converters with outputs from 2 to 95Vdc, at 50 to 600 Watts.

The VI-HAM consists of a full-wave rectifier, a proprietary high-frequency zero-current switching (ZCS) boost converter, and includes active inrush current limiting, over temperature and short circuit protection, control, and housekeeping circuitry. For further information click here
