DC/DC Converters for Cableways: Combined with Autonomous Transport
Context and Background
Electrification is advancing without restrictions in cable way technology. Nowadays, this includes seat heating, LEDs for interior and exterior lighting, monitors, and speakers. Even 5V USB charging ports or Wi-Fi connectivity are no longer a rarity. Whether in alpine tourism areas or urban regions, cable ways are no longer used solely in the mountains but also in subtropical cities, where they place particularly high demands on the power supply. Extreme altitudes and climatic conditions require an innovative design to ensure maximum operational safety. Whether in the frigid mountains or the tropical climates of popular tourist destinations, our DC/DC converters deliver reliable performance in various conditions and come in a compact size.
Reliable Power Supply for Cable Ways at the Highest Level
Our robust DC/DC converter, the 145E-13.8-SD, is utilized in a 3S gondola on a glacier in the Austrian Alps. It reliably provides stable 13.8VDC power to secondary consumers while simultaneously charging the backup battery. The converter operates using supercapacitors, with an input voltage range that varies from less than 20VDC when discharged to as high as 100VDC when fully charged. The DC/DC converter 145E-13.8-SD guarantees a stable output voltage of 13.8VDC, regardless of the significant fluctuations in supercapacitor voltage – even at more than 3,000 meters above sea level. At the highest alpine border crossing in Switzerland, another of our powerful converters, the 154DH-27-ON, is used in a cable way, regulating the on-board voltage from 48VDC to a stable 27VDC output voltage.
Trust in future-proof technology that guarantees safe and efficient energy supply, even in harsh high-altitude environments.
Innovative Solutions for Cable Ways and Autonomous Transportation
The combination of gondolas with seamless transitions to autonomous passenger transportation offers an especially eco-friendly solution for urban mobility. In areas where cable ways don’t have direct access, an autonomous vehicle takes over the transportation without passengers needing to transfer. For a cableway utilizing a supercapacitor with a charging voltage of 51VDC, we employ our galvanically isolated DC/DC converter, the 729-48-SD. This converter provides an output voltage of 48VDC and operates with a notably low input voltage range of 12VDC to 32VDC. The DC/DC boost-buck converter 257LEX-24-SD is applied in the drivetrain. In this case the converter must provide a stable 24VDC output in a particularly low operating range of 7VDC to 35VDC.
