Mid-power Maxi, Mini, and Micro modules for military and aerospace applications

Vicor has introduced a number of new mid-power products to its families of pre-defined modules Maxi, Mini, and Micro DC-DC converters. These modules are well suited to the demands of military and aerospace environments, allowing designers to select standard products better tailored to their specific power and current requirements. Still incorporating Vicor’s patented low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS), these products’ inherent low noise greatly reduces the design effort and filtering costs required for power converters to meet various conducted emissions requirements, such as MIL-STD-461. With these new offerings, Vicor can now provide an...

New MIL-COTS 28 V DC-DC V•I Chip™ Modules: 20% more power and 1/3 the volume in a rugged, miniature package

Vicor’s new MIL-COTS 28 V DC-DC V•I Chip modules consists of a 28 Vdc input PRM™ regulator and a family of VTM™ current multipliers with output voltages from 1 to 50 Vdc. The PRM and VTM chipset provides the full functionality of a DC-DC converter with high efficiency and higher power density, fast transient response, low noise, and flexible thermal management. With each module weighing only 15 grams and measuring just 32.5 x 22 x 6.6 mm, the chipset offers specific advantages for designing power systems in mission-critical portable and airborne applications. A PRM...

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

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...

28 V Military COTS Input Filter

March 1, 2005
By

The M-FIAM5B: this recently introduced 28 V input filter provides superior transient immunity to its predecessors. Requiring minimal external components when used with Vicor’s 2nd Gen DC-DC converters the M-FIAM5B meets MIL-STD-704E input requirements as well as providing EMI filtering to MIL-STD-461E. Other features include a 20 A output capability, inrush current limiting and remote enable/disable. Measuring only 56 x 58 x 13 mm The M-FIAM has proved popular in ground mobile military systems.  Download a datasheet
