Crada final report for crada number ORNL98-0521: development of. An electric bus inverter based on ORNL auxiliary resonant tank (ART) soft-switching technology

摘要

The Power Electronics and Electric Machinery Research Center (PEEMRC) of Oak Ridge National laboratory (ORNL) has for many years been developing technologies for power converters for motor drives and may other applications. Some of the research goals are to improve efficiency and reduce audible and electromagnetic interference noise generation for inverters and the driven loads. The converters are being required to produce more power with reduced weight and volume, which requires improvements in heat removal from the electronics, as well as improved circuit designs that have fewer electrical losses. PEEMRC has recently developed and patented a soft-switching inverter topology called an Auxiliary Resonant Tank (ART), and this design has been tested and proven at ORNL using a 10-kW laboratory prototype.
