Description
The STEVAL-IHM021V2 demonstration board
implements a 100 W, 3-phase inverter for field-
oriented control (FOC) of permanent magnet
synchronous motors (PMSM).
The 3-phase inverter bridge is based on the
STD5N52U power MOSFET with enhanced fast
body-drain recovery diode in a DPAK package,
and the L6390. The L6390 represents the latest in
high-voltage half-bridge gate drivers featuring an
integrated comparator for hardware protection
against overcurrent, overtemperature, etc. The
device also features an embedded operational
amplifier suitable for advanced current sensing.
The STEVAL-IHM021V2 has been specifically
designed to achieve fast and accurate
conditioning of the three shunt resistor-based
motor current feedback network, matching the
requirements typical for high-end applications
such as field-oriented motor control.
As an alternative to the STD5N52U, the
STGD6NC60HD or STGDL6NC60DI IGBT
devices may also be used on the board for
STEVAL-IHM021V2
frequencies lower and higher than 10 kHz,
respectively. In either case, no replacement of the
switches driving the network is required.
The board is compatible with 110 and 230 Vac
mains, and includes a power supply stage using
the VIPer12A-E (in buck configuration) to
generate the +15 V and +3.3 V supply voltage
required by the application. The board can be
interfaced with the STM3210B-EVAL (STM32
microcontroller demonstration board) through the
dedicated motor control connector.
