ELECTRONIC SUB-SYSTEM AND POWER GENERATION SYSTEM FOR POWERING VARIABLE FREQUENCY ELECTRICAL DEVICES

摘要

An electronic sub-system (104, 204, 304) is presented. The electronic sub-system includes (104, 204, 304) a first alternating current (AC)-direct current (DC) converter (110, 210) and one or more second AC-DC converters (112, 212, 215) electrically coupled to the first AC-DC converter (110, 210) via a DC-link (114, 214). The electronic sub-system (104, 204, 304) is electrically coupled to at least one of an auxiliary power source (108, 208) to receive an auxiliary electrical power or a local power grid (116) to receive a local grid power, and wherein the at least one second AC-DC converter (112, 212) is configured to supply a variable frequency electrical power to at least one variable frequency electrical device (106, 206) at a frequency determined based on a level of the auxiliary electrical power, the local grid power, or a sum of the auxiliary electrical power and the local grid power.
