Description
The STEVAL-IPE008V1 demonstration board
shows how to design a 3-phase meter using
STPM01 as measuring device and a
VIPer12ADIP-E as SMPS (switch mode power
supply). The STPM01 is a metering ASSP
implemented in an advanced 0.35 µm BCD6
technology. It is designed for the effective
measurement of active, reactive, apparent
energies, V_RMS, I_RMS, instantaneous voltage and
current, and frequency in power line systems that
use the current transformer, Rogowski coil and/or
shunt principle. This device can be used as a
standalone on-board metering device in single-
phase energy meter applications or as a
peripheral in a microprocessor based single- or 3-
phase meter. In a standalone configuration
STPM01 outputs a pulse train signal having a
frequency proportional to the active power used,
while in peripheral mode STPM01 is used in a
microprocessor based application. In this case,
measured data are read at a fixed interval from
the device internal registers by means of SPI
interface processed by a microcontroller.
