Structural method for increasing the accuracy of converting parameters of the complex resistance of traction power supply objects into a time-frequency signal

Abstract

The article discusses the principles of operation of quasi-balanced bridge converters with closely inductive couplings between the arms, having an extended range and maximum sensitivity by creating a parametric auto-resonant mode by changing the supply frequency of the measuring bridge. To reduce the errors of the conversion elements, a conversion algorithm based on a mathematical model is proposed, and a schematic diagram of a capacitive sensor parameter into code using a microcontroller is given.
