Online DC Voltage Measurement by Using DC-to-DC Converters

Article Preview

Abstract:

In order to measure the terminal voltage of a lead-acid battery online, a DC-to-DC converter – MC34063 is used to convert the D.C. input voltage to the supply voltage of measurement circuit. A three-terminal adjustable regulator of TL431A is used to generate a standard reference voltage for the A/D converter of the Microchip MCU – PIC16F873A. This D.C. voltage meter takes advantage of high accuracy of measurement and high stability.
