STEVAL-IHM004V1 Datasheet, PDF (1/4 Pages) STMicroelectronics – BLDC & AC motor control Power driver board 1 KW

Features
■ Quick to set up, to install and easy to run
■ Inverter stage IGBT short circuit rugged based
■ Design is re-usable (the ORCAD source files
are available for free)
■ Several kinds of applications with six-step
commutation or 6-signal PWM (sine wave-
modulated) outputs, including: 3 Phase AC
Induction motor control, 3 Phase BLDC/AC PM
motor control (6-step sensorless), 3 Phase
BLAC PM motor control (sinusoidal driven, with
Hall sensors)
■ Optimized layout to provide very low level of
interference between the Power and the Signal
noise
■ Modular approach with three different power
board module (300W, 1kW, 3kW)

Data Brief
STEVAL-IHM004V1
Description
The general hardware architecture of the
reference design kit is based on an Inverter
topology suitable to efficiently drive three types of
motors: "3 Phase BLDC/AC Permanent Magnet
(in six-step mode)" , "3 Phase AC Induction" and
"3 Phase BLAC PM motor (sinusoidal driven)"
plus a plug-in control board, based on ST7FMC
MCU.
The inverter bridge is made by six IGBTs short
circuit rugged rated at 10uS with different option
of current capability in relationship to the power
needed by the customer final application. The
driving of the bridge is made by three IGBTs
drivers (suited in the control board) with High
Side/Low Side integrated functionality in a single
chip with also several protections. The supply of
the power is implemented using the Viper, a
Vertical Intelligent Power Enhanced Regulators
which combines an optimized, high voltage,
Vertical Power MOSFET with state-of-the-art
PWM circuitry.
