Khaligh receives U.S. Patent 8,853,888 for multiple-input DC-DC converter

Assistant Professor Alireza Khaligh (ECE/ISR) has been issued U.S. Patent 8,853,888 for a multiple-input DC-DC converter.

The converter is capable of power diversification among different energy sources with different voltage-current characteristics. It can operate bidirectionally in buck, boost and buck-boost modes and provides a positive output voltage without the need for a transformer.

Multiple-input converters can combine the advantages of different energy sources, such as photovoltaic cells, fuel cells, wind power devices, batteries, ultracapacitors and other renewable energy sources, with different voltage and current characteristics to provide power and for optimal energy/economic use, while increasing the reliability of a system.

These converters are useful in grid-connected integrated hybrid generation systems, fuel cells, micro grid-based telecom power systems, uninterruptible power supplies and electric and hybrid electric vehicles.
