Power supplies for simultaneously providing AC and DC power

摘要

A power supply (100) for providing power to a load includes a first subconverter (106) having input terminals for coupling to a first input power source and output terminals and a second subconverter (110) having input terminals for coupling to a second input power source and output terminals. The first subconverter is configured to supply an AC current and an AC voltage at its output terminals. The second subconverter is configured to supply one of a substantially constant DC current and a substantially constant DC voltage at its output terminals. At least one of the output terminals of the first subconverter is coupled to at least one of the output terminals of the second subconverter. The power supply is configured to supply the AC current, the AC voltage, the substantially constant DC current and the substantially constant DC voltage substantially simultaneously to the load (102).
