Abstract

This diploma thesis is focused on the power part design of accumulator locomotive charger. PWM rectifier is used as a charger. PWM rectifier is directed rectifier with minimum distortion factor. Principal operation and properties are described in the first part of the work. Then the individual parts of construction design are analyzed. It is for example: dimensioning of equipment, electric schematics design, selection of semiconductors, analysis of losses, cooling system design atc. The work contains selection and description of all constructional parts. 3D model was created in software for 3D simulation. On this model we can see all components and their location. The components which should be made are drawn and dimensioned in supplement of diploma thesis.
