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:
- step-up, boost, or
- step-down, buck, or
- buck & boost.
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:
| Type of non-isolated DC-DC converter | Input | Output | Efficiency | Customer’s field of activity |

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 (lead-acid battery) |
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 (fuel cell) |
24V / 4A / 100W | 90% | Polar expedition / France |
| BOOST | 20V to 28V (lead-acid battery) |
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.
