High Voltage DC DC Converter Fit for Purpose

A converter can be broadly defined as a device regulating the voltage level between the source and load by stepping it up or down. It consists of a series of components including capacitors, transformers, transistors, inductors and others that ensure the voltage remains clean and stable.

Over the years, the performance, size demands, thermal management, reliability, durability and power range of converters improved significantly. AEPS converters are the manifestation of such improvements and now it is you who can benefit from them directly!

Rigorously tested for excellence, our converters have an incredible range of applications in some of the most demanding industries where failure is simply not an option. Find yours among the many converter types we offer, or consult our specialist who will help you make the best choice!

Our High Voltage DC-DC Converters Can Be Put to Use in the Following Situations

The attributes of our converters make them usable in conditions where a more regular equipment would be prone to failure. Below you will find a few examples of possible application fields - but remember, the list is far from exhaustive!

  • Altitudes above 15 km. Durability against acceleration, low pressure, radiation and extreme temperatures is a must here. Compact sizes and good cooling is a must. Planes, drones, aerial laboratories – our converters are suited for all of them.
  • Altitudes between 5-15 km. Similar equipment requirements as above still apply here.
  • Altitudes up to 5 km. Resistance against all sorts of weather, dust and moisture is paramount here, as is mechanical durability. Our converters will not fail you.
  • Land transport. Cars, trains, you name it. Fast acceleration and vibrations are something a piece of equipment must handle, in addition to all sorts of weather and temperature changes.
  • Telecommunication equipment, such as connecting towers, communication centres etc. Low profile models with bottom case cooling are best suited for this purpose.
  • Mining. Shocks, vibrations and high temperatures are common in this field. Our converters will manage.
  • Supercomputers. These demand high efficiency and parallel operation capabilities, which our converters deliver.
  • Arctic or desert equipment (both moving and stationary). Freezing cold or scorching heat are no obstacle for our equipment.
  • Street signs, visual advertising. Low weight and high efficiency are demanded in this field – and we provide.
  • Radar technology. Low weight and profile, parallel operation capability and efficiency are a must in applications like these.
