STEVAL-IHM032V1 150 W inverter featuring the L639x and STGD3HF60HD for 1-shunt based sinusoidal vector control and trapezoidal scalar control Features ■ Compact size ■ Wide-range input voltage ■ Maximum power up to 150 W at 230 Vac input ■ STGD3HF60HD: 4.5 A, 600 V very fast IGBT ■ Compatibility with other power switches in DPAK packages (the STD5N52U and STGD6NC60HD, for example) ■ AC or DC bus voltage power supply connectors ■ Connector for interfacing with the STM3210xxEVAL board, STEVAL-IHM022V1, and STEVAL-IHM033V1 with alternate functions (current reference, current limitation/regulation, method selection, current boost) ■ Efficient DC/DC power supply (15 V, 3.3 V) ■ Suitable both for sinusoidal FOC and trapezoidal BLDC drive ■ Single-shunt current reading topology with fast operational amplifier (with offset insertion for bipolar currents) ■ Hardware overcurrent protection with boost capabilities ■ Temperature sensor ■ BEMF-detection network for BLDC drive ■ Current regulation/limitation network for BLDC drive ■ Hall sensor/quadrature encoder inputs Applications ■ Dishwasher pumps ■ Refrigerator compressors ■ Fans October 2011 STEVAL-IHM032V1 Description The STEVAL-IHM032V1 demonstration board is a 3-phase inverter designed to perform both the field-oriented control (FOC) of sinusoidal-shaped back-EMF permanent magnet synchronous motors (PMSMs) and trapezoidal control of brushless DC (BLDC) motors with or without sensors, with nominal power up to 150 W. This flexible, open, high-performance system based on the L639x and STGD3HF60HD is specifically designed to achieve fast and accurate conditioning of the current feedback, thereby matching the requirements typical of high-end applications such as field-oriented motor control. The board is compatible with 110 and 230 Vac mains, and includes a power supply stage with the VIPer12A-E (in flyback configuration) to generate the +15 V and +3.3 V supply voltage required by the application. Finally, the board can be interfaced through a dedicated connector with the STM3210xx-EVAL (STM32 microcontroller demonstration board), STEVAL-IHM022V1 (highdensity, dual motor control demonstration board based on the STM32F103ZE microcontroller), and with the STEVAL-IHM033V1 (control stage based on the STM32F100 microcontroller suitable for motor control).
