Weight-to-price indicators of electromagnetic systems single-phase transformers and reactors with twisted magnetic circuits

New technical proposals for improvement by changing the configuration and position in the space of active elements in order to reduce the material capacity and increase the reliability of single-phase transformers and reactors are presented. Based on mathematical models with partial or integral optimization criteria and a set of independent and dependent control variables, the optimal mass and cost parameters of single-phase electromagnetic systems variants that differ in the structure and configuration of the active elements are determined.
