Motor drives is a widely used technology, offering many advantages, such as exceptional speed control and flexibility. Improvement of reliability and efficiency has become a great research interest. Toward this direction and considering the major recent developments in supercapacitor technology, the use of bidirectional energy recovery converters has been introduced in various industrial applications...
Common variable speed drives usually do not feature regenerative braking. The energy produced during deceleration is dissipated through braking resistors. In this paper, a bidirectional converter designed for use with variable speed drives, adding the capability of regenerative braking, is presented. Hardware design and control algorithms are analyzed and comparison with similar proposals is made...
Reliability is one of the most important parameters in aircrafts. In this paper, a method for the calculation of reliability (i.e. number of failures / 106 hours) of a three-phase full-bridge inverter, which is employed in the dynamic waste heat recovery system of an aircraft, is presented. The main factors for the reliability analysis that have to be considered is the topology of the inverter, the...
