STEVAL-IHM035V2

STEVAL-IHM035V2 3-phase high voltage inverter power board for FOC and scalar motor control based on the STGIPN3H60 (SLLIMM-nano) Data brief Description The STEVAL-IHM035V2 is designed to drive a high voltage/low power 3-phase brushless motor, either synchronous or asynchronous (PMSM and ACIM). It provides a compact solution in terms of size and efficient power dissipation, thanks to the ST IPM STGIPN3H60 (SLLIMM-nano). With the on-board MC-connector, the demonstration board can also be interfaced with any ST MCU control board in order to implement a complete motor drive. Features Nominal power: up to 100 W Compatible with 3.3 V and 5 V control board Single shunt resistor for current reading On-board temperature sensor Overcurrent protection with boost/disabling capability For six-step drives: Current limitation/regulation network BEMF detection network MC connector Compatible with sinusoidal and trapezoidal control RoHS compliant August 2013 DocID025149 Rev 1 1/6 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagrams STEVAL-IHM035V2 1 Schematic diagrams Figure 1: STEVAL-IHM035V2 circuit schematic AM11140v1 2/6 DocID025149 Rev 1 Vbus U2 STGIPN3H60 C13 16 17 PhaseU L LIN U Vboot U 15 2.2u F 25V SD/OD 2 +15V 14 18 PhaseU H HIN U P 13 Vcc U 12 19 CIN Phase A CIN U C14 470n F 25V 11 20 PhaseV L LIN V N U C15 10 MOTOR PhaseV H HIN V 9 21 Vcc V Vboot V CON3 GND GND 2.2u F 25V 1 Phase A 8 22 2 CUR OP- OP- V Phase B Phase B 7 3 Curr feedba ck OPOUT Phase C 6 GND CUR OP+ OP+ GND 23 J6 C16 N V 5 24 PhaseW L Vdd M icro LIN W Vboot W 4 PhaseW H HIN W 3 2.2u F 25V Vcc W 25 Phase C W 2 R36 Eme rgency SD/OD 1 Test points 1 26 R37 4.7k GND N W 0 Eme rgency TP1 Vshunt PhaseU H TP2 R38 PhaseU L TP3 R39 R40 910 R41 PhaseV H TP4 1k 22 CIN PhaseV L TP5 C19 PhaseW H 910 TP6 R43 33p F 10V PhaseW L TP7 C17 C18 0.47 BLDC Mtd sel TP8 R42 2.2n F 10V 22n F 10V CUR OP+ BLDC OCL TP9 1k CUR OP- BLDC Curr. ref.
