A case study. Case study Marine DC power supply. A case study of electric boats. Case study A high-tech hybrid boat powered by solar energy: Sobe Sunset Case study DC-DC CONVERTERS FOR FUEL CELL APPLICATIONS Case study 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. Case study 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. Case study Cranes 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. Case study Industrial Elevator Electronic counterweight and peak shaving can be provided by a bidirectional DC/DC converter-based solution working with batteries and/or supercapacitors. Case study Passengers Elevator 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. Case study Hybrid boats 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. Case study Off-grid hydrogen generation 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.
