Energy-efficient power regulators for electric railway vehicles

This study aims at validation of the power regulation parameter for electric railway vehicles for effective use of electrical potential of energy sources. Based on analysis of electromagnetic processes with the use of suggested energy parameters and mathematical modeling method the assessment of energy efficiency was performed for semiconductor power regulators for alternating and direct current electric traction drives. Power balance and obtained mathematical equations for calculation of its components allow improving the education content of educational institutions due to eliminating methodological inconsistencies. The suggested technical solutions for continuous and full use of the electrical potential of overhead systems and self-generated power supply sources ensure their advantage in terms of structure, energy efficiency and electromagnetic compatibility.
