STEVAL-IHM005V1

BLDC & AC Motor Control

Power Driver Board 3KW

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)

Applications

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.
