Instantaneous conduction and switching losses in two-level voltage source inverters [PDF]
, 2017 A mathematical model is derived which allows to compute instantaneously the conduction and switching losses in two-level voltage source inverters (2L-VSIs) regardless of the employed modulation scheme.

CONDUCTIVE HEARING LOSS IN BIGHORN SHEEP [PDF]
Journal of Wildlife Diseases, 1995 In January 1993 we simulated a conductive hearing loss in three Mexican bighorn sheep (Ovis canadensis mexicana) by placing bone wax or saline solution in their ear canals. Our objective was to test whether lesions of the external auditory canal caused by psoroptic mites (Psoroptes ovis) may lead to conductive hearing loss in bighorn sheep. We assessed

A Modified Topology of Two-Switch Buck-Boost Converter
IEEE Access, 2017 Two-switch buck-boost (TSBB) is one of the non-isolated dc-to-dc converters that can change its mode from among buck, boost, and buck-boost modes. Changing its mode is possible by controlling gate signals. This paper presents a novel modified topology of

Evaluation of a dual-T-type converter supplying an open-end winding induction machine [PDF]
, 2013 The multilevel inverter is a promising technology compared to two-level inverters in the applications of ac-drives and smart-grid applications. In this paper, a dual-T-type three-level inverters is used to drive an open-end winding induction machine. The

Analytical Calculation of the Residual ZVS Losses of TCM-Operated Single-Phase PFC Rectifiers
IEEE Open Journal of Power Electronics, 2021 Triangular-current-mode (TCM) modulation guarantees zero-voltage-switching across the mains cycle in AC-DC power converters, eliminating hard-switching with a minor ${\approx} {30}{\%}$ penalty in conduction losses over the conventional continuous ...
