Modeling of Power Losses in High-Power Motor Drives
Electrica, 2023 The efficiency of the system decreases with increasing switching frequency in high-power density industrial driving applications. In order to increase the system efficiency, reliability, and power quality in a high-power drive system, power losses are becoming more crucial to calculate precisely in the industrial drive. In this study, the switching and

Power transformer additional load losses separation procedure [PDF]
Zbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2011 The proposed procedure is based on the fact that total transformer losses (PLL1,n), determined by short circuit test, can be separated into two components: the eddy current losses in the windings (PEC1,n) and stray flux losses (PSL1,n) in iron parts of ...

The Price of Synchrony: Resistive Losses due to Phase Synchronization in Power Networks [PDF]
, 2012 We investigate the total resistive losses incurred in returning a power network of identical generators to a synchronous state following a transient stability event or in maintaining this state in the presence of persistent stochastic disturbances.
