Features
Description
The STEVAL-ISV003V1 is a demonstration board
which implements the microinverter concept and
is designed to optimize the power production of
each single solar panel by means of DC-AC
conversion. The conversion system is capable of
both grid synchronization and maximum power
point tracking (MPPT) thanks to the use of an
advanced control algorithm implemented in the
32-bit STM32 microcontroller. The MPPT function
is based on the perturb and observe (P & O)
concept which seeks the best operating point of
the panel, thus maximizing the energy produced
under any environmental condition. The grid
synchronization algorithm has the advantage over
standard solutions of a decoupled control of
active and reactive power. The STEVAL-
ISV003V1 demonstration board uses a high-
frequency (HF) isolated DC-DC converter with
interleaved current and an optimized full-bridge
DC-AC inverter. The typical solar panel voltage is
first stepped up to about 400 V and then
converted into AC to create a sinusoidal output.
An LED display provides a user-friendly interface
for the end user which allows the monitoring
and/or modifying of some of the main operating
parameters. Two modes of operation are available
and can be selected to allow either open-loop
operation or closed-loop operation in
synchronization with the grid.

In open-loop mode the sinusoidal reference is
created internally by means of a standard lookup
table, while in closed-loop mode, a sinusoidal
voltage feedback which is proportional to the grid
voltage is used. This system can be connected to
a 50 Hz network (STEVAL-ISV003V1) and to a 60
Hz network (STEVAL-ISV003V2), based on local
requirements. The RS-232 interface can be used
for serial data transfer of specified voltage, current
and current signals.
