Abstract :
This paper introduces an on-line electric power test system in high character, strong function, and convenient operation based on single chip microprocessor (SCM) and CPLD technology. This system uses 16 bit high speed σ-Δ A/D converter, which designing a three phase voltage, current synchronization field test system. SCM selects low power MSP430F149IPAG with rich inter chip materials, which saving many more outer electric circuit and reducing system cost. This paper mainly introduces parts of in detail. Through experiment, system precision of voltage and currency is 0.1 level, which completely meet design command, and has widely application value and using prospect.
