The STEVAL-IHM021V2 demonstration board implements a 100 W, 3-phase inverter for field-oriented control (FOC) of permanent magnet synchronous motors (PMSM). The 3-phase inverter bridge is based on the STD5N52U power MOSFET with enhanced fast body-drain recovery diode in a DPAK package, and the L6390. The L6390 represents the latest in high-voltage half-bridge gate drivers featuring an integrated comparator for hardware protection against overcurrent, overtemperature, etc. The device also features an embedded operational amplifier suitable for advanced current sensing. The STEVAL-IHM021V2 has been specifically designed to achieve fast and accurate conditioning of the three shunt resistor-based motor current feedback network, matching the requirements typical for high-end applications such as field-oriented motor control. As an alternative to the STD5N52U, the STGD6NC60HD or STGDL6NC60DI IGBT devices may also be used on the board for frequencies lower and higher than 10 kHz, respectively. In either case, no replacement of the switches driving the network is required. The board is compatible with 110 and 230 Vac mains, and includes a power supply stage using the VIPer12A-E (in buck configuration) to generate the +15 V and +3.3 V supply voltage required by the application. The board can be interfaced with the STM3210B-EVAL (STM32 microcontroller demonstration board) through the dedicated motor control connector.

The STEVAL-IHM033V1 is a control stage demonstration board based on the STM32F100CB microcontroller. The board has been designed as an evaluation environment for motor control. The demonstration board can be used together with the STM32 PMSM single/dual FOC SDK v3.0 and an STMicroelectronics demonstration powerboard equipped with an MC connector (such as the STEVAL-IHM032V1) for a complete motor control evaluation and development platform.

The STEVAL-IHM040V1 is a 3-phase permanent magnet brushless motor driver designed to drive a motor using either the six step or field oriented control (FOC) commutation technique. The board can operate from an AC mains of either 115 or 230 VACnominal at 50/60 Hz, or from a DC input voltage between 150 and 350 VDC. The board can supply a continuous output current of 0.5 ARMSto the motor. The circuit consists of three main blocks. The first is the digital control block, which uses the STM32F100C8T6 microcontroller to implement the control algorithms and to generate the control signals for the power stage. The main outputs of the control block are the signals for the power stage. The second block is the power stage, a 3-phase inverter bridge implemented using the STGIPN3H60 SLLIMM-nano intelligent power module. The SLLIMM includes the 6 IGBTs, gate drivers and level shift required to interface the logic signals from the digital control to the motor terminals. The SLLIMM also provides a hardware overcurrent shutdown and an op-amp used to scale and bias the current sensing. The third block is the power supply, which employs the VIPER16 to convert the high voltage DC bus to a regulated 15 V supply that supplies the SLLIMM and analog circuitry on the board. The 15 V supply also supplies an L78L33 linear regulator that provides the 3.3 V logic supply for the microcontroller. Two firmware control programs are available, one for six steps and one for FOC, which run on the same hardware platform.

The STEVAL-IHM045V1 system evaluation board is a 3-phase inverter designed to perform field oriented control (FOC) of sinusoidal-shaped back-EMF PMSMs with or without sensors, with nominal power up to 100 W. This flexible, high-performance design consists of a 3-phase inverter bridge based on the STGIPN3H60A SLLIMM™-nano (small low-loss intelligent molded module) IPM, 3-phase inverter, 3 A / 600 V very fast IGBT and the VIPer06 fixed frequency offline converter from the VIPer™ plus family. The system is specifically designed to achieve fast and accurate current feedback conditioning, 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 an auxiliary power supply stage with the VIPer06 to generate the +15 V and the +3.3 V supply voltages required by the application. Through a dedicated connector, the board can be interfaced with the STM3210B-EVAL, STM32100B-EVAL, STM3210E-EVAL, STM320518-EVAL, STM3220G-EVAL, STM32303C-EVAL, STM3240G-EVAL (STM32 microcontroller evaluation boards), STEVAL-IHM022V1 (high density dual motor control evaluation board based on the STM32F103ZE microcontroller), STEVAL-IHM039V1 (Dual motor drive control stage based on the STM32F415ZG microcontroller) and the STEVAL-IHM033V1 (Control stage based on the STM32F100CB microcontroller suitable for motor control).

The STEVAL-IHP007V1 evaluation board is a power line communication module addition to the STEVAL-ILH007V1 HID ballast module. It provides functions for the management of street lighting network architecture in the CENELEC A-B-D bands. The module is based on an STM32F103CBT7 ARM Cortex-M3 microcontroller and an ST7580 PSK narrow band power line modem with up to 28.8 kbps data rate. The embedded MCU can be easily replaced with an equivalent 48-pin MCU from the STM32F0, STM32F2, STM32F3 families with a few changes. The module is designed to work with the STEVAL-ILH007V1 HID module, but can be associated with other lighting driver boards with a standard serial communication port. Note that this board only functions in a network with an EVALKITST7580-1 board designated as the master; this is achieved via UART commands.

The STEVAL-ILD003V1 demonstration board is designed to propose a low-cost analog dimmer topology using a sensitive SCR TS820-600FP. The dimmer can drive typical low-consumption lamps, particularly CFL and LED dimmable lamps. Through-hole technology is used for the most important components such as LC filter, gate resistor, turn-on delay capacitor, etc., in order to allow board modification, if needed. The STEVAL-ILD003V1 eliminates flickering thanks to its continuous current applied through the sensitive SCR gate. This dimmer could easily replace a standard low-cost analog Triac light dimmer using a Diac-controlled circuit.
