Comprehensive Power Losses Model for Electronic Power Transformer
IEEE Access, 2018 The electronic power transformer (EPT) has higher power losses than the conventional transformer. However, the EPT can correct the power factor, compensate the unbalanced current, and reduce the line power losses in the distribution network.

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 ...

Influence of Gear Loss Factor on the Power Loss Prediction [PDF]
Mechanical Sciences, 2014 Abstract. In order to accurately predict the power loss generated by a meshing gear pair the gear loss factor must be properly evaluated. Several gear loss factor formulations were compared, including the author's approach. A gear loss factor calculated considering the load distribution along the path of contact was implemented. The importance of the
