VPT High-Reliability DC-DC Converters and EMI Filters for Military Applications


VPT’s products guarantee genuine military-grade, high-reliability DC-DC converters, electromagnetic interference (EMI) filters, and other power accessories qualified to MIL-PRF-38534 Class H and Class K.

VPT offers product lines ideal for applications such as military ground vehicles, weapon systems, unmanned systems and avionics.

With a wide variety of power conversion product offerings, high efficiencies, wide temperature ranges and DLA standard microcircuit drawings (SMDs) for most models, VPT’s power conversion products are suitable for any military specification.

Rugged, high-reliability power DC-DC converters

VPT’s VXR series of rugged, high-reliability DC-DC converters and EMI filters is optimised for a broad range of applications, from military ground vehicles to manned and unmanned aircraft that endure adverse environmental conditions such as severe vibration, shock and temperature cycling.

VPT’s patent-pending epoxy encapsulated V-SHIELD® packaging is also highly resistant to chemical, solvent and salt environments, making it fully compatible with high-volume manufacturing processes such as wave solder, cleaning solvents, high-pressure sprays and aqueous wash.

Avionics and military DC-DC converters

Ranging from 1W-120W and able to withstand temperatures of up to 125°C (no power de-rating necessary), VPT’s DV Series of products are designed to meet rigid military specifications and are 100% hermetic, with a variety of circuit protection features.

The DV series is suitable for both military and avionics applications.

Isolated DC-DC converters for efficient power systems

VPT’s isolated DC-DC converters save weight, heat, and cost to create an efficient power system in addition to their family of non-isolated, synchronous, buck regulated point of load DC-DC converters.

The company’s continual advancements in power conversion technology deliver many unique advantages across its product lines, including:

  • Maximum reliability thick-film hybrid technology
  • Innovative rugged high-reliability architecture
  • Proprietary epoxy encapsulation package availability
  • Full operation over wide temperature ranges
  • High level of EMI performance
  • High-power densities
  • Lightweight design

Screening for rugged environments

Each VPT product line offers several grades of environmental screening.

Depending on the product series selected, tests performed include a non-destructive bond pull, internal visual, temperature cycling, constant acceleration and particle impact noise detection (PIND).

Screenings are also available for stabilisation bake, pre burn-in electrical and burn-in, 100% final electrical, hermeticity, radiography and external visual.
