STEVAL-IHM021V2
100 W, 3-phase inverter based on the L6390 and UltraFASTmesh™
MOSFET for speed FOC of 3-phase PMSM motor drives
Data brief
Features
■ Wide range input voltage
■ Maximum power: up to 100 W at 230 Vac input
■ STD5N52U power MOSFET (4.4 A, 520 V)
■ Compatible with other power switches in DPAK
packages (i.e. the STGD6NC60HD or
STGDL6NC60DI)
■ 15 V auxiliary power supply connector
■ Motor control connector for interfacing with
STM32-based control stages
■ Three shunt resistor-based motor current
sensing network
STEVAL-IHM021V2
■ Target applications: refrigerator compressors
frequencies lower and higher than 10 kHz,
respectively. In either case, no replacement of the
switches driving the network is required.
and dishwasher pumps
■ RoHS compliant
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.
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
