3-phase motor control demonstration board featuring IGBT

intelligent power module STGIPS10K60A

Introduction

This document describes the 1 kW 3-phase motor control demonstration board, featuring

the STGIPS10K60A: 600 V - 10 A IGBT Intelligent power module. The demonstration board

is a 3-phase inverter for driving an induction motor or PMSM motors up to 1000 W. The main

target of this application is to show users the performance of the ST 25L-SDIP (25-lead,

small dual inline package), IPM - STGIPS10K60A.

The board has been designed to be compatible with a single-phase supply from 90 VAC to

220 VAC, or for DC voltage from 125 VDC to 350 VDC. The document is associated with the

release of the STEVAL-IHM027V1 demonstration board (see Figure 1).

1.3 Safety and operating instructions

1.3.1 General terms

Warning: During assembly, testing, and normal 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 if the

kit or components are improperly used or incorrectly

installed. The kit is not electrically isolated from the AC/DC

input. The demonstration board is directly linked to the mains

voltage. No insulation is ensured between accessible parts

and high voltage. All measuring 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 shock from occurring

as a result of touching any SINGLE point in the circuit, but

does NOT prevent shock when touching two or more points

in the circuit. Do not touch the demonstration board after

disconnection from the voltage supply; several parts and

power terminals, which contain energized capacitors, must

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 considered as suitably qualified people who are familiar with the installation, use, and

maintenance of power electronic systems.

1.3.2 Demonstration board intended use

The STEVAL-IHM027V1 demonstration board is designed for demonstration purposes only

and must not be used for any commercial purposes. The technical data, as well as

information concerning power supply conditions, must be taken from the relevant

documentation and strictly observed.

1.3.3 Demonstration board installation

The installation of the demonstration board must be in accordance with the specifications

and the targeted application.

●The boards contain electro-statically sensitive components that are prone to damage

through improper use. Electrical components must not be mechanically damaged or

destroyed

●Avoid any contacts with other electronic components

●During the motor drive converters must be protected against excessive strain. In

particular, no components are to be bent or isolating distances altered during the

course of transportation or handling

System introduction UM0969

8/57 Doc ID 17665 Rev 1

1.3.4 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. A system architecture which supplies power to the

demonstration board must 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).

2 Board description

2.1 System architecture

A generic motor control system can be basically schematized as the combination of three

main blocks (see Figure 2):

●Control block: the main task of this block is to accept user commands and board\motor

configuration parameters. The control block provides all digital signals to implement the

right motor driving strategy. The STM3210B-EVAL, ST demonstration board, based on

an STM32 microcontroller, can be connected to the STEVAL-IHM027V1 thanks to the

onboard motor control connector

●Power block: this is based on three-phase inverter topology. The heart of the power

block is the STGIPS10K60A integrated intelligent power module which contains all the

necessary active components. Please refer to the STGIPS10K60A datasheet (see

References 1) for more information

●Power supply block: able to work from 90 VAC to 220 VAC or from 125 VDC to 350

VDC. Please refer to Section 3: Hardware setting of the STEVAL-IHM027V1, to

properly set the jumpers according to the required application

The STEVAL-IHM027V1 includes the power supply and the power block.
