DESCRIPTION
The
STPM01
measurement of active energy in a power line
system using the Rogowski and/or Shunt
principle. This device can be implemented as a
single chip 1-phase energy meter or as a
peripheral measurement in a microprocessor
based 1-phase or 3-phase energy meter.
The STPM01 consists, essentially, of two parts:
the analog part and the digital part. The former, is
composed by preamplifier and 1
st
order
Σ
D AD
converter blocks, Bandgap voltage reference,
Lowdrop voltage regulator and a pair of DC buffer,
the latter, is composed by system control, clock
generator, hard wired DSP and SPI interface.
There is also a OTP block, which is controlled
is
designed
for
effective
through the SPI by means of a dedicated
command set. The configured bits are used for
testing, configuration and calibration purpose.
From a pair of
Σ
D output signals coming from
analog section, a DSP unit computes the amount
of consummated active, reactive and apparent
energy, RMS values of voltage and current value.
The results of computation are available as pulse
frequency and states on the digital outputs of the
device or as data bits in a data stream, which can
be read from the device by means of SPI
interface. This system bus interface is used also
during production testing of the device and/or for
temporary or permanent programming of bits of
internal OTP.
In the STPM01 the calibration is very easy: an
output signal with pulse frequency proportional to
energy is generated, this signal is used to enable
the calibration of the energy meter.
When the device is fully configured and calibrated,
a dedicated bit of OTP block, can be written
permanently in order to prevent accidental
entering into some test mode or changing any
configuration.
