Title: The Innovative Contributions of Roland Huempfner
Introduction
Roland Huempfner is a notable inventor based in Munich, Germany. He has made significant contributions to the field of power supply systems, particularly in data centers. With a total of seven patents to his name, Huempfner's work reflects a deep understanding of electrical engineering and innovative design.
Latest Patents
One of Huempfner's latest patents is a power supply system for a data center. This system includes one or more solid-state transformers (SST), first stage DC-DC converters, and second stage DC-DC converters. The SSTs are designed to convert medium-voltage Alternating Current (MVAC) or medium-voltage Direct Current (MVDC) inputs into a first low-voltage Direct Current (LVDC) output. The first stage DC-DC converters then convert this output to a second LVDC output, which is further processed by the second stage DC-DC converters to produce a third LVDC output. This final output is utilized to supply power to servers within the data center's ICT load area.
Another significant patent by Huempfner is a power system that cascades output terminals of a power supply or DC-to-DC unit to increase output voltage. This design aims to reduce current between the power supply or DC-to-DC unit and the DC-to-AC unit, addressing cost and loss issues associated with cabling. The innovative approach also minimizes the number of cables required, thereby reducing overall system costs.
