Energy management
solutions for industrial applications
Epic power Supercapacitor Converter (ESC) are a family of products based on the epic power non-isolated converter family combined with a custom designed supercapacitor module of 60 kJ
The DC/DC converter is responsible for the power flow to and from the supercapacitor module while the module acts as a high-cycle energy buffer. Depending on the targeted industrial application different firmware can be implemented in the converter. Each configuration leads to a different industrial product:
- Energy recovery (ERS): ESC-60kJ-ERS
- Peak Shaving (PKS): ESC-60kJ-PKS
- Electronic counterweight (ECW): ESC-60kJ-ECW
- Fast Emergency Supply for drives (FES): ESC-60kJ-FES
Working with supercapacitors
Benefits
- High power density

Applications
ERS
Energy Recovery System
with supercapacitors
a braking energy recovery system, fully compatible with any regenerative application
contact us- Automatically detects when there is generation and absorbs it before the braking resistor does.
- Returns the energy stored in consumption trips or standby.
PKS
Peak shaving
with supercapacitor
avoid peak power consumption from the grid using energy storage based on supercapacitor
contact us- Discharge enabled by external controller when peak cut is required.
- Automatically charges the supercapacitors from mains and braking energy.

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.
