|VIA PFM™ Power Modules - Vicor introduces its high-density, low-profile, integrated VIA PFM™ AC-DC front-end power modules. The VIA PFM is a highly advanced 400 W AC-DC converter operating from a rectified universal AC input which delivers an isolated and regulated safety extra low voltage (SELV) 24 V secondary output. This unique, ultra-low profile module incorporates AC-DC conversion, integrated filtering, and transient surge protection in a chassis-mount or PCB-mount form factor. The VIA PFM enables a versatile two-sided thermal strategy, which greatly simplifies thermal design challenges.
|Isolated Regulated DC-DC Converter - The DCM is an isolated, regulated DC-DC converter, operating from an unregulated, wide range input to generate an isolated output. With its high frequency zero voltage switching (ZVS) topology, the DCM converter consistently delivers high efficiency across the input line range. Modular DCM converters and downstream DC-DC products support efficient power distribution, providing superior power system performance and connectivity from a variety of unregulated power sources to the point of load.
|VI Chip® BCM® Bus Converter - Vicor's VI Chip® BCM® Bus Converter supplies 1.2 kW at 48 V with 98% peak efficiency and 1880 W/in3 power density. Breakthrough performance – 4X the density of competing solutions – enables efficient, high voltage DC distribution infrastructure in datacenter, telecom, and industrial applications.
|AN:001 — Configuring Vicor IBC Converters with niPOLs
The niPOLs within IBA forego isolation and high–ratio voltage transformation in order to improve cost effectiveness, and they depend upon a nearby bus converter to supply isolated power at a low voltage. The BCM or IBC can be placed at the power entry point on the board. This will provide safety isolation from the higher backplane voltage as well as free up board space at the point–of–load.
AN:002 — PRM/VTM Parallel Operation
This applications note describes the steps needed to create a current sharing higher power array using two PRM-AL and VTM pairs in a parallel configuration. If the application requires more than two PRMs in parallel, please contact Applications Engineering for additional information.
AN:003 — Powering Multiple VTMs with a Single PRM
This Applications Note discusses the design practices for using Vicor's V•I Chip Pre-Regulator Module and Voltage Transformation Module to meet the challenge of power systems that require lower voltages, more current, and multiple voltages within one system. Vicor's V•I Chips can address these challenges.
AN:005 — FPA Printed Circuit Board Layout Guidelines
Factorized Power with V•I Chips enable system density to keep pace with technology by providing layout flexibility and high power density. More importantly, V•I Chips allow a power conversion system to be factorized or separated into its constituent functions.
AN:006 — A Filter Solution for the BCM
The Bus Converter Module (BCM) is a member of Vicor's Factorized Power Architecture family of V•I Chips. It provides an isolated intermediate bus voltage to power non-isolated point-of-load (POL) converters from a narrow input range DC source.
AN:007 — Using VTMs as 26 – 55 V Input Bus Converters
The Voltage Transformation Module (VTM) is a fundamental building block of Factorized Power Architecture (FPA). This new power conversion architecture separates the functions of the DC-DC converter — regulation, isolation, and transformation — into two building blocks.
AN:008 — V•I Chip BCM Bus Converter Thermal Management
The purpose of this Applications Note is to determine the power capability of the BCMs given certain ambient temperature and air flow conditions plus heat sink options.
AN:009 — V•I Chip Soldering Recommendations
V•I Chips are intended for reflow soldering assembly. The information contained in this document defines the processing conditions required for successful attachment to a PCB. Failure to follow the recommendations provided can result in aesthetic and functional failure of the module.
AN:016 — Using BCM™ Bus Converters in High Power Arrays
This application note provides methods and guidelines for designing BCMs into high power arrays.
AN:017 — RoHS-Compliant Through-Hole V•I Chip Soldering Recommendations
RoHS compliant, through-hole full size V•I Chips are intended for wave soldering assembly. The information contained in this document defines the processing conditions required for mounting a full size V•I Chip to the PCB using wave soldering or hand soldering.
AN:018 — Providing a Constant Current for Powering LEDs using the PRM and VTM
Light Emitting Diodes (LEDs) require a constant current for proper operation. In order to use the PRM and VTM to power an LED, it is necessary to modify the operation of the PRM to provide a regulated current. This application note provides guidelines for implementing that constant current source using the chipset.
AN:022 — MIL EMI and Transient Solutions
28 Volt defense applications must meet a number of noise and power related standards such as MIL-STD-461, MIL-STD-704, and MIL-STD-1275.
AN:024 — Accurate Point-of-Load Voltage Regulation Using Simple Adaptive Loop Feedback
This application note explains the adaptive loop regulation concept and the design procedure to achieve good voltage regulation for a simple PRM/VTM combination.
