Netradiční napájecí zdroj pro měřicí zařízení v místě bez přívodu proudu

Abstract

The purpose of this work is to describe the design and realization of power supply for the measuring device that measures the voltages of feedback path traction currents and surrounding conductive objects. The source of the measuring device is directly supplied from voltages of reverse path traction currents. In the solutions are analyzed input voltages proportion, on which is based the all design solution. The work contains information dealing with the selection of a suitable backup battery and a related draft charging circuit, stabilizers and control circuits. The work also describes the practical realization of the all design and it is accompanied annex containing datasheets of components and diagrams of circuits. In the solutions are presented calculations of including components.
