STEVAL-IHM017V1

STEVAL-IHM017V1 100 W 3-phase inverter for BLDC sensorless motor evaluation board Data Brief Features ■ Wide range input voltage ■ Maximum power up to 100 W ■ 4.4 A, 520 V power MOSFET included ■ Compatible with power MOSFETs in IPAK packages ■ 15 V auxiliary power supply connector ■ Programming and debugging support via 10pin ICC connector ■ Three potentiometers for runtime settings ■ Start/stop button ■ Reset button ) s ( ct u d o r P e t e l o Description ) (s This evaluation board is a complete development platform for BLDC sensorless motor applications with nominal power up to 100 W. t c u Based on a cost effective, flexible and open design, it includes a 3-phase inverter bridge based on the STD5NK52ZD-1 power MOSFET in the IPAK package and an ST7MC 8-bit microcontroller with 16 Kbyte internal Flash memory. d o r s b O STEVAL-IHM017V1 buck converter to generate the voltage reference for the driver and the microcontroller. P e t e l o The system has been designed to drive a 3-phase brushless motor with permanent magnet rotor exploiting trapezoidal sensorless control. s b O The STEVAL-IHM017V1 features complete hardware for developing motor control applications based on ST7MC peripherals including motor control peripheral (MTC). It uses an in-circuit communication (ICC) standard interface to connect to the host PC via in-circuit debuggers/programmers such as the inDART-STX board from SofTec Microsystems™. The board is designed to support a bus voltage of 230 Vac and up to 100 W of input power. Also included is a power supply stage with the VIPer12A-E as the January 2008 Rev 1 For further information contact your local STMicroelectronics sales office. 1/5 www.st.com 5 NTC F1 FUSE 3A 5 120/230-Vac 120/230VAC J9 t + D21 BRIDGE_2KPB** CAP NP 0.22uF 275V-X2 C10 - C1 R25 CON2 R24 100K-1/2W 4 2 1 +15V see manual transil TR1 STTH106 2 1 D2 2.2uF/25V C2 1 1N4148 D1 BF2 BE1 BE2 BD2 BC1 BC2 BB2 BA1 BA2 2 3 FB 10uF/35V 35V C3 3 100nF/50V C9 +15V GNDBF1 1 1 GNDBD1 1 1 GNDBB1 1 1 Q8 STD5NK52ZD-1 Q7 STD5NK52ZD-1 C4 22nF/50V D3 BZX84C15 2 1 4 VDD 4 0.23V LSCS + 8 7 6 5 D7 STTH108 SOURCE DRAIN RES SET 3 Q12 STD5NK52ZD-1 Q11 STD5NK52ZD-1 Q10 STD5NK52ZD-1 Q9 STD5NK52ZD-1 BEMFC BEMFB BEMFA 22nF/400V C8 TOKO 00499 L1 1mH/350mA IC1 VIPER12ADIP R10 0.1R-2.5W 1 D20 82K D19 82K D18 R17 82K 1 R15 1 R12 2 STTH106 2 STTH106 2 STTH106 2 D6 BZX85C16 1 3 D5 BZX85C5V1 Vin R18 82K 2 R R R R 2 GND Title: Vout L78L05ACZ IC2 1 +5V 1uF/16V 16V C6 Size SYSTEMS LAB Wednesday, June 13, 2007 Document Number Organisation name: Date: CON3 R4 12K R3 330K R2 680K Power Board STD5NK52ZD ) s ( ct u d o R66 1.2K R16 82K R65 1.2K R13 82K R64 1.2K C5 2 100uF/25V +15V 2 r P e A B C 15-5A Phase-Main D Neutral-Main 1 2 2 3 2 3 2 3 2 3 2/5 2 s b O t e l o 100K-1/2W 3 P e ) (s 2 d o r t c u t e l o s b O 3 1 1 2 3 M.Di Guardo 1 of 1 Approved by: G.Rasconà Drawn by: Phase C Phase B Phase A ALL THE RESISTORS ACCURACY MUST BE
