DC Microgrid
There are plenty of cases where unnecessary and inefficient AC/DC and DC/AC conversions can be avoided by using bidirectional DC/DC conversion. Distributed generation mainly based in small-scale solar energy.
Installations is becoming a reality. In the meantime, home appliances and consumption is more and more in DC (led lights, modern home appliances, electric vehicles, screens, battery powered devices,…). Resilient neighbourhood energy communities are becoming a necessity in times of climate change, wildfires and aging AC distribution infrastructure. In this particular scenario, DC conversion technology is of paramount importance for efficient, robust and simple novel infrastructure, all in DC. Thomas A. Edison would be happy to hear that the War of Currents is not really over.

It is estimated that 80% of demand for electricity in residential and commercial buildings are natively in DC. AC/DC conversions are inefficient, especially when renewable energy sources and energy accumulators are part of the picture.
Tested technology
In this scenario, bidirectional DC/DC conversion plays a major role in exchanging energy among the interchangeable sources and loads both at the individual home level or at neighbourhood level. Our technology has proven useful in DC microgrids featuring special characteristics that makes it simple to integrate in such an application, in particular in terms of modularity, overall protection and control simplicity.
Case studies
Off-grid solar panel powered solution to feed hydrogen fuel cells through isolated DC/DC converters. Each converter provides MPPT per solar string to achieve highest efficiency.
Flexible solution for grid-connected hydrogen fuel cells through isolated DC/DC converters. High efficiency, robustness and easy parallelization for infinite combinations of power requirements.
AGVs & shuttles (supercapacitor powered)
Bidirectional DC/DC converters applied to shuttles allow energy consumption from supercapacitors and charge from the grid with only one component. Electrified monorails become unnecessary in warehouses.
Logistics – AGVs (battery powered)
Reduction in size, cost and weight in battery powered industrial vehicles through DC/DC converters. DC motors are removed in favour of AC more standard and smaller solutions.
A hybrid powered solution for cranes achieve reductions in fuel consumption, size of generator and braking resistor bank. Energy stored is used by a DC/DC converter to counterweight the power requirements and save the braking energy.
Electronic counterweight and peak shaving can be provided by a bidirectional DC/DC converter-based solution working with batteries and/or supercapacitors.
The use of less power from the grid or the reduction of the overall energy consumption can be achieved with battery and/or supercapacitor powered DC/DC converter-based solutions.
Combine a traditional fuel generator with a battery- powered system based on DC/DC to make a hybrid boat. Charge your batteries from the wind and move the boat freely without the need for it in the harbour.
