DC/DC converters – EPC
EPC systems have shaped the new generation of bidirectional DC/DC Converters. EPCs (Epic Power Converters) are suitable for a large number of applications ranging from industrial ones to those in the field of renewable energies.
Bidirectional high-efficient DC/DC power converters. With a wide range of voltage levels in both sides, the EPCs are capable of managing power in both directions.
Why a bidirectional DC/DC Converter?
As a typical application the low side voltage can be connected to batteries or ultracapacitors to feed any drive (VVVF) directly through the DC link.
This allows the system to continue in operation in case of lack of mains supply. It also allows for off-grid applications where there is no three-phase mains available or, for example, in automatic warehouses when the platforms are moving off-grid.
Features DC DC converter
- Bidirectionality. Managing energy flow in both directions
- Ultra-high efficiency, achieved with silicon carbide transistor technology.
- Scalable with easy paralellization.
- Galvanic isolation.
- Maintains the DC link voltage in the absence of main supply.
- Soft pre-charge of the DC link. Suitable to switch ON and OFF the drive as many times as required in order to save energy and life expectancy of the inverter.
- Automatic change of power flow to stabilize either input or output voltage without stopping voltage regulation.
- CAN communication available to implement voltage or current control and transmit relevant measurements of operation parameters (voltage, power, current, temperatures, etc.).
- Customized versions available upon request.

Case studies
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.
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.
