STEVAL-IHM019V1

STEVAL-IHM019V1 Complete inverter for low power 3-phase asynchronous motors demonstration board Data Brief Features ■ Voltage Input range 115 VAC to 230 VAC 50 Hz or 60 Hz ■ Total output power 50 W ■ High efficiency ■ Switching PWM frequency 12 - 22 kHz ■ Compliant with EN61000-6-3 and EN61000-6-2 ■ Possibility to use two motor types: – 2-phase motor two sinusoidal voltage waves restored with a phase displacement of 90° between them – 3-phase motor three sinusoidal voltages with phase displacement of 120° among them AM01597v1 STEVAL-IHM019V1 where high efficiency is required and low cost per solution is a must. Applications ■ Water pumps for heating systems in singlefamily houses ■ High efficiency surplus water pump for home appliance white goods, like washing or washerup machines ■ High efficiency transfer pumps for outlet condensation water in gas furnace application Description This demonstration board implements a 3-phase inverter for low power asynchronous electric motors or permanent magnet AC motors up to 50 W. Nominal input voltage for inverter is 230 VAC - standard single phase connecting. This 3phase inverter is based on 8-bit ST7FMC motor control controller. Main target of this demonstration board is a very low-cost effective 3-phase inverter for permanent magnet AC motor, but with certain modification of software it can be used also for 3-phase asynchronous motors November 2008 Rev 1 For further information contact your local STMicroelectronics sales office. 1/4 www.st.com 4 Vbus 10nF C27 R21 10k C29 1nF 100k C5 680uH 47k R12 L3 1 592-275 RV2 1 2 3 4 5 6 7 8 9 10 D1 + 10k R13 R16 10k +5V 100R R8 R27 470R +5V DZ1 C19 10n 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 5R1 R32 100nF 100nF pot HIN1 LIN1 HIN2 R2 150k R1 150k C26 M_GND pot 150uF/400V + C6 C25 M_GND R24 220R M_GND +5V speed _se le ction MCIC/PB3 PD0/OCMP2_A/MCPWMW/AIN11 OAP/PC2 RESET OAN/PC3 Vdd_0 AIN6/MCCFI1/OAZ Vss_0 VAREF MCCREF/PC4 ST7FMC1K4T6 2 P6KE400A B250C1000DIL - J3 ICC connector Speed 680uH 150n-X2 ON/OFF i ndi ca tor LED D14 4n7 Y C2 4n7 Y C1 L2 4 3 (HS)MCO3 MCO2(HS) (HS)MCO4 MCO1(HS) (HS)MCO5 MCO(HS) MCES Vpp/ICCSEL OSC1 PD7(HS)/TDO OSC2 PD6(HS)/RDI AIN0/PWM0/PA3 PD5/AIN15/ICCDATA AIN1/ARTIC1/PA5 PD4/EXTCLK_A/AIN14/ICCCLK MCVREF/PB0 PD3/ICAP_1A/AIN13 MCIA/PB1 PD2/ICAP2_A/MCZEM/AIN12 MCIB/PB2 PD1(HS)/OCMP1_A/MCPWMN/MCDEM U5 47k 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 R11 10k M_GND sw R10 Phase_C 10 mH L1 R31 10k 4 1 Phase_B C15 47n R26 sw C22 30pF C21 Y 1 16MHz Control_part SW1 10k R5 +5V Phase_A 330n-X2 C4 30pF H_sp LSCS LIN3 HIN3 LIN2 1 2 3 1 2 3 Start/Stop CON J2 CON ON/OFF swi tch Output_p hase s 230V~ J1 592-275 RV1 1 2 NTC1 15R 3 2 100n C13 8 7 6 5 FB VDD U1 R6 12k R4 470k R3 470k VIPer12AS Drain4 Source2 Drain3 Source1 Drain2 Drain1 F1 2A 1 2 Vbus HV 3 4 D4 L4 + C8 10uF 50V HIN1 LIN1 +15V HIN3 LIN3 +15V HIN2 LIN2 +15V STTH1L06U 600V 1A D6 1000uH 200mA C7 22nF BZX85C15 LL4148 D2 + 470n C28 470n C23 470n C18 C14 100uF 35V 1 2 3 4 1 2 3 4 1 2 3 4 D7 C9 220nF STTH1L06U 600V 1A D3 L6388 LIN Vboot HIN HVG Vcc OUT GND LVG U6 L6388 LIN Vboot HIN HVG Vcc OUT GND LVG U4 L6388 LIN Vboot HIN HVG Vcc OUT GND LVG U3 BZX85C18 15VDC 8 7 6 5 8 7 6 5 2u2/16V C24 2u2/16V C20 C10 100n R17 47R R15 300R R14 47R R9 300R R7 47R LL4148 D13 LL4148 D12 LL4148 D11 R29 300R R25 47R R23 300R R22 47R R20 300R R19 47R LL4148 R18 300R D10 LL4148 D9 LL4148 D8 8 IN U2 TP7 TP6 TP5 TP4 TP3 TP2 LIN1 1 +5V HIN3 LIN3 HIN2 LIN2 HIN1 OUT L78L05AC Test_pins TP1 BZX85C5V1 D5 3*_half-bridge +15V C16 2u2/16V 15VDC 8 7 6 5 +325VDC +15V HV +5V_source C11 HV Q6 STGP6NC60HD Phase_C Q5 STGP6NC60HD Q4 STGP6NC60HD Phase_B Q3 STGP6NC60HD Q2 STGP6NC60HD Phase_A C17 R28 0.1R R30 0.1R LSCS 100nF/400VAC +325VDC +5VDC +5V 22uF/10V C12 Q1 STGP6NC60HD 100n Figure 1. 2 1 2/4 GND GND GND GND 1 2 3 6 7 Rectifier,_EMC,_Power_source,_I/O Circuit schematic STEVAL-IHM019V1 Circuit schematic Schematic AM01598v1 STEVAL-IHM019V1 2 Revision history Revision history Table 1.
