A simple way to enhance compatibility for IAMS and FIAMS

A simple way to enhance compatibility for IAMS and FIAMS

Vicor’s Input Attenuator Modules (IAM) and Filtered Input Attenuator Modules (FIAM) are DC front-end filters that provide EMI filtering, transient protection, inrush limiting and surge suppression to various military and industrial standards. They are found in military vehicles, industrial and telecommunications environments and similar applications. The Military (MI) and Industrial (VI) IAMs are compatible with MI/VI-200/J00 DC-DC converters while Military (M) and Industrial FIAMs are compatible with the Micro, Mini and Maxi DC-DC converters. However there may be occasions when running different combinations of (F)IAM and DC-DC converter becomes desirable. For example a combination...

Vicor V·I Chip™ modules improve ATE system design and save space

Vicor engineers recently helped an Automated Test Equipment (ATE) customer achieve an advanced distributed power supply architecture that delivers space savings, simplified mechanical design and several other benefits. The ATE has 13 DC outputs and draws 1.2 kW from a 110 – 220 Vac mains input. The ATE electronics had previously been powered from an externally mounted centralised architecture power supply. By exploiting the V·I Chip module family’s high power density, efficiency and flexibility, the power supply assembly has now been implemented on a single board that slots directly into the ATE chassis and...

380 Vdc to 48 Vdc High-Efficiency Powertrain Conversion

380 Vdc to 48 Vdc High-Efficiency Powertrain Conversion

Complete power-train conversion, from 380 Vdc to a standard 48 Vdc rail, can be achieved with a new Bus Conversion Module (BCM™) from V•I Chip Corporation, The VIB0002TFJ features a MHz-switching zero-voltage switching (ZVS™), zero-current switching (ZCS™), sine amplitude converter (SAC™) to achieve a high power density of 1,150 W/in3 and over 95% efficiency. In eco-array configurations, efficiency is over 90% from a 10% light-load, to full-load at multi-kW power levels. Established factorised power architecture components supply an easy and efficient step from the 48 Vdc rail to high-current, sub-1 V loads. The exceptional...

Vicor Helps Power Solar Boat

Vicor Helps Power Solar Boat

Built in stainless steel, the stunning, 25-metre boat is manufactured by Kopf-Solarschiff for use as a sightseeing ferry with a capacity of up to 110 passengers and a range of up to 90 kilometres. A charge regulator, designed and manufactured by Uhlmann Solar with specialist support from Vicor is used to convert power from the solar panels into two batteries operating at different voltages: a 24 V battery is used to power the lighting and audio system, whilst a 300 V battery provides the drive power for the boat. Uhlmann Solar used four Vicor...

Reduce Your Power System Volume by 75%

The combination of 840 W/in3 power density and 94.5% efficiency from a half-inch square, ‘half-chip’ V•I Chip package enables the VIB0101THJ to achieve a 75% reduction in overall power-system volume compared to equivalent power-rated modules. The first of the new 1/32nd bricks, the VIB0101THJ Bus Converter Module (BCM™) provides an easy, fast and flexible approach to achieving higher overall system efficiency combined with reduced board-space and cost. Rated at 120W, the VIB0101THJ operates from a 38 to 55 Vdc primary bus to provide an isolated 12 V nominal, unregulated secondary. This can be used...

Understanding Forced-Air Cooling

Understanding Forced-Air Cooling

Forced air cooling can make a significant difference to thermal management, improving the heatsink-to-air thermal resistance by as much as an order of magnitude with the right combination of hardware. Making the right choices, however, means interpreting and matching the convection data for both the heatsink and the fan. The first step is to calculate the maximum heatsink-to-air thermal resistance for the system: next, the operating airflow through the heatsink is determined. Airflow from the fan, expressed in cubic feet per minute (CFM), is plotted against the curve for pressure drop, shown in inches...
