1 kW three-phase motor control demonstration board
featuring L6390 drivers and STGP10NC60KD IGBT

Introduction
This document describes the 1 kW three-phase motor control demonstration board featuring
the L6390 high and low-side drivers and the STGP10NC60KD IGBT. The demonstration
board is an AC/DC inverter that generates a three-phase waveform for driving three or two-
phase motors such as induction motors or PMSM motors up to 1000 W with or without
sensors.
The main device presented in this user manual is a universal, fully evaluated, and populated
design consisting of a three-phase inverter bridge based on the 600 V STMicroelectronics™
IGBT STGP10NC60KD in a TO-220 package mounted on a heatsink, and the L6390 high-
voltage high-side and low-side driver featuring an integrated comparator for hardware
protection features such as overcurrent and overtemperature. The driver also integrates an
operational amplifier suitable for advanced current sensing. Thanks to this advanced
characteristic, the system has been specifically designed to achieve an accurate and fast
conditioning of the current feedback, therefore matching the typical requirements in field
oriented control (FOC).
The board has been designed to be compatible with single-phase mains, supplying from
90 VAC to 285 VAC or from 125 VDC to 400 VDC for DC voltage. With reconfiguration of the
input sourcing, the board is suitable also for low-voltage DC applications up to 35 VDC. This
document is associated with the release of the STEVAL-IHM023V2 demonstration board
(see Figure 1 below).

Safety and operating instructions
2.3.1
General terms
Warning: During assembly, testing, and operation, the demonstration
board poses several inherent hazards, including bare wires,
moving or rotating parts, and hot surfaces. There is a danger
of serious personal injury and damage to property, if the kit
or components are improperly used or installed incorrectly.
The kit is not electrically isolated from the AC/DC input. The
demonstration board is directly linked to the mains voltage.
No insulation has been placed between the accessible parts
and the high-voltage. All measurement equipment must be
isolated from the mains before powering the board. When
using an oscilloscope with the demonstration board, it must
be isolated from the AC line. This prevents a shock from
occurring as a result of touching any single point in the
circuit, but does NOT prevent shocks when touching two or
more points in the circuit. Do not touch the demonstration
board after disconnection from the voltage supply, as several
parts and power terminals, which contain energized
capacitors, need to be allowed to discharge.
All operations involving transportation, installation and use, as well as maintenance, are to
be carried out by skilled technical personnel (national accident prevention rules must be
observed). For the purpose of these basic safety instructions, “skilled technical personnel”
are suitably qualified people who are familiar with the installation, use and maintenance of
powered electronic systems.
2.3.2
Demonstration board intended use
The STEVAL-IHM023V2 demonstration board is a component designed for demonstration
purposes only and is not to be used for electrical installation or machinery. The technical
data as well as information concerning the power supply conditions should be taken from
the documentation and strictly observed.
2.3.3
Demonstration board installation
The installation and cooling of the demonstration kit boards must be in accordance with the
specifications and the targeted application.
●
The motor drive converters are protected against excessive strain. In particular, no
components are to be bent or isolating distances altered during the course of
transportation or handling.
No contact must be made with other electronic components and contacts.
The boards contain electro-statically sensitive components that are prone to damage
through improper use. Electrical components must not be mechanically damaged or
destroyed.

2.3.4
Electrical connections
Applicable national accident prevention rules must be followed when working on the main
power supply with a motor drive. The electrical installation must be completed in accordance
with the appropriate requirements.
2.3.5
Demonstration board operation
A system architecture which supplies power to the demonstration board should be equipped
with additional control and protective devices in accordance with the applicable safety
requirements (e.g. compliance with technical equipment and accident prevention rules).
