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.
A few examples of non-isolated DC-DC converters, recently engineered by Elecdan Converter at the request of customers:
|Type of non-isolated DC-DC converter||Input||Output||Efficiency||Customer’s field of activity|
|BUCK||30V to 50.4V
(12 lithium batteries)
|24V / 15A / 360W||97%||Automation / Germany|
|BOOST, proportionally controllable by “0 to 5V”||18V to 25V||26V to 48V / 600W
0 → 26V
2.5V → 37V
5V → 48V
|94%||Robotics / France|
|BUCK & BOOST||35V to 58.8V
(14 lithium batteries)
|56V / 6A / 400W||95%||Computing / USA|
|BOOST||10V to 14V
|18V / 300W||96%||Land transport / France|
|Reversible BUCK & BOOST||40V to 80V
(reversible aquatic generator with propeller)
|56V / 6A / 400W (battery)||95%||Sailboats (accumulation & propulsion) / USA|
|BOOST||40V to 56V
(4 x 12V lead-acid batteries)
|72V / 12.5A / 900W||96%||Railways / France|
|BOOST||3V to 5V
|24V / 4A / 100W||90%||Polar expedition / France|
|BOOST||20V to 28V
|48V / 500W / 100 cm3||95%||525 robotic trolleys / France|
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.
