A Guide to Vicor’s Unique Online Power Supply Design and Selector Tools: PowerBench

Vicor’s PowerBench offers designers the capability to design online a power module or complete power supply to meet their exact requirements. What makes this unique is that these custom products are manufactured on the same manufacturing line, using the same components and manufacturing processes as our standard products. This gives the power supply designer a custom part with the quality, price and delivery assurances they would expect from a standard product. In fact, PowerBench is the umbrella for a suite of packages: in addition to the custom design packages mentioned there are a number...

New Off-line, High-density V•I Chip™ Bus Converter

Vicor has launched a high-voltage V•I Chip bus converter with a power density of greater than 1000 W/in³ (part number B384F120T30). This BCM™ module is a high-efficiency (>95%), Sine Amplitude Converter™ (SAC) operating from a 360-400 Vdc (384 Vnominal) primary bus to deliver an isolated low voltage secondary. The 12 V (nominal) output can be paralleled for high current outputs or connected in series to create a 48 Vbus, making the converter ideal for use in high performance server and telecom ac-dc SMPS and enabling major power density improvements in the post-PFC dc-dc stage....

Optimising Processing Real Estate

Optimising Processing Real Estate

The drive to create metadata processing server systems plus the parallel push for increased port density and triple-play (voice/video/internet) traffic handling in telecommunication systems places greater demands on power management architectures. The problem: inefficient power architectures Traditional designs using AC to 12 Vdc Silver Box followed by 12 V to 1.x Vsynch buck have run aground in terms of system power density and efficiency due to a combination of distribution bus losses and fundamental restrictions in topology performance as processor voltages reach sub-volt levels. Higher voltage (48 V or 350/380 V) bus voltages reduce...

Torpedo Control System

Torpedo Control System

Torpedos are very demanding applications, requiring very reliable and rugged components (including the power supply). Their shape and size also mean that the space left for the power supply element can be very small and the wrong shape to fit a standard box solution! For one Vicor customer, operating in the defense and large systems electronics sectors, in particular in the underwater systems field. One of their most successful applications is a heavy-weight torpedo used as a multipurpose weapon designed to be launched by submarines or surface vessels. The customer required a complete, non-standard...

Head-down Display Equipment for Harsh Environments

Head-down Display Equipment for Harsh Environments

In recent years aircraft flight and navigational information have migrated from conventional round mechanical dials mounted on the instrument panel, to software-dependent electronic displays, capable of showing many types of information. In particular, a head-down display is a rear projection information system that displays essential flight information, helping the pilots “artificially” see their surroundings and the ground. One Vicor customer specializes in the area of high technology electronic systems, telecommunication accessories and aircraft harnesses, which satisfy the needs of the international defence industry. They are now developing a new head-down display designed to operate...

Multiple Inputs Power Supply Architecture

Multiple Inputs Power Supply Architecture

Some electronic systems, such as field communication shelters or portable emergency equipment, must be able to operate from a variety of power sources, for example worldwide AC (85–264 Vrms), vehicle battery power, or portable generator sets, in both the 12 V or 24 V standards. In addition, these systems may also require backup power from auxiliary batteries in case the primary source is interrupted. An example of this power supply architecture is shown in the figure below (click for larger image). For AC line use, a front-end module accepts a universal AC input and...

Solar-powered Car

Solar-powered Car

By easing power-circuit design and providing reliable operation even in tough desert conditions, a Vicor DC-DC module has helped a solar-powered car to compete in Solar Challenge races in Australia. The 1,800 mile race challenges power designs with severe restrictions on energy, space and heat dissipation. Faced with designing a power circuit for a solar-powered car, to compete in the Solar Challenge across 1,800 miles of Australian desert, a team of young engineers turned to Vicor DC-DC converters. Their challenge was to provide stable and reliable supply voltage to the on-board PC and telemetry...
