EXTREMELY-SPARSE PARALLEL AC-LINK POWER CONVERTER

摘要

An extremely-sparse parallel AC-link universal power conversion device is provided that is capable of converting between various power schemas using a reduced number of switches. The number of heat-dissipating elements and the overall size of the power converter are reduced, while the power density is increased. The expected failure rate is lowered, increasing the reliability of the power conversion device and reducing maintenance frequency and operating cost.
