Why should you be interested in Elecdan Converter’s patented, high-efficiency, non-isolated DC-DC converters?

The use of non-isolated converters, formerly quite uncommon, has now become widespread, particularly in the computer, telecommunications and electronic equipment industries.

We observe that 9 times out of 10, when converting DC-DC electrical energy, it is not useful to isolate the “zero of the output voltage” from the “zero of the input voltage”.

Tip: Starting with powers ≥ 100W, it is very advantageous to adopt a common “zero” at the input and the output, using a non-isolated DC-DC converter:

  • Much less energy losses thanks to a very high efficiency (typically 92% to 99%),
  • Decreased volume of the converter,
  • Input energy saving, delivered by the generator (battery, fuel cell, photovoltaic module, etc.),
  • Less parasitic calories to evacuate,
  • Increased reliability,
  • Reduced costs.

In addition, our non-isolated boost (step-up) converters prevent any starting-up overcurrent, thanks to an instantaneous switching. This enables, for example, the use of a motor with a very high starting current.

Types of non-isolated converters:

If you require an isolated converter, see our offers with powers ranging from 15W to 1250W, for input ranges between 9V and 1000V.

A few examples of non-isolated DC-DC converters, recently engineered by Elecdan Converter at the request of customers:

Buck converters are also called step-down converters.
Boost converters are also called step-up converters.

Among our products, “step-up voltage regulators” are non-isolated DC-DC boost converters.
