STMicroelectronics

The STEVAL-IHM034V2 is a complete motor control kit solution for the evaluation of STMicroelectronics® wide product portfolio tailored to applications where it is necessary to drive, simultaneously, two motors in sensorless field oriented control (FOC) and perform active power factor correction (PFC) through digital control of a single-stage boost DC-DC converter. Typical applications include in-room air conditioners (RACs), where this ST solution can drive the compressor, outdoor fans and PFCs. The microcontroller unit consists of STMicroelectronics’ ARM™ Cortex-M3 core-based STM32F103RC, which is capable of carrying out all of the previously-mentioned tasks simultaneously. The board is compatible with the STM32F2 series and with the ARM™ Cortex-M4 core-based STM32F4 series. Motor 1 is powered by the onboard SLLIMM™ (small low-loss intelligent molded module) STGIPS20C60. Motor 2 can be powered by an external STMicroelectronics power stage, such as those that can be evaluated using the STEVAL-IHM021V1, STEVAL-IHM024V1, STEVAL-IHM032V1 or STEVAL-IHM035V1 evaluation boards. Simultaneously, the same microcontroller unit drives the onboard boost PFC stage designed with the STGW35HF60W ultrafast IGBT or, alternatively, for high switching frequencies the STW38N65M5 MDmesh V Power MOSFET, and STTH15R06D Turbo2 ultrafast diode or the STPSC1206D Schottky silicon carbide diode. The STEVAL-IHM034V2 can be used together with the STM32 permanent magnet synchronous motor (PMSM) single/dual FOC software development kit (SDK) v3.2 or later and its compatible PFC v1.0 firmware plug-in.

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-IHM042V1 evaluation board is designed as a complete dual motor field-oriented control (FOC) demonstration platform featuring STMicroelectronics’ ARM Cortex™-M4F 32-bit core-based STM32F303CC microcontroller with floating point support and two fully integrated DMOS L6230 3-phase motor drivers. It is designed as an integrated evaluation environment for motor control applications in the range of 8 V - 48 V DC bus voltage (extendable up to 52 V) and nominal power up to 10 W for each motor drive. The design exploits the computational power of the STM32F303CC microcontroller with 48 KB of internal SRAM and 256 KB Flash, 4 ADCs, 2 DACs, 7 comparators, 4 operational amplifiers with programmable gains, SWD debugging, as well as the L6230 DMOS driver’s 2.8 A output peak current, non-dissipative overcurrent detection/protection, cross-conduction protection, uncommitted comparator, thermal shutdown, and undervoltage lockout. The STEVAL-IHM042V1 is equipped with a USB-to-serial interface, specifically for real-time data exchange implemented by an STM32F103C8 pre-programmed with the STM32 Virtual COM Port firmware. The ST Link in-circuit debugger and programmer is embedded in the board, allowing the user to program and debug the STM32F303CC microcontroller directly with a USB cable using a compatible toolset.

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-IHP002V2 demonstration board implements a PLM smartplug node which allows monitoring the energy consumption of a mains plug and controlling any kind of load in on/off mode through a relay. The board is based on the STM32F103CB microcontroller, the ST7540 PLM module and the STPM01 mono-phase energy metering IC. The board is designed to fit a standard "503" wall box. The voltage, current, power, active energy and the output status can be sent to a PLM data concentrator through a power line communication network on request. Moreover, if the power consumption changes, it is sent asynchronously to the data concentrator.

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-IHT005V2 is designed as a complete solution proposal for home appliance applications based on STMicroelectronics™ components. Special emphasis is placed on demonstration of a robust full 3.3 V solution, based on 4 kV level in class A during an IEC-61000-4-4 (burst) test. The board also allows designers to evaluate the feasibility of AC switch control with a 3.3 V supply. Gate currents can be measured and compared to the information given in application note AN2986. STEVAL-IHT005V2 is based on the recently-introduced 48-pin, 32-bit STM32F100C4T6B MCU running at 24 MHz (RC user-trimmable internal RC clock), featuring 16 kBytes of Flash memory, 12-bit A/D converter, 5 timers, communication interfaces, and 4 kBytes of SRAM. The power supply circuitry is based on the VIPer16L, an offline converter with an 800 V avalanche-rugged power section, operating at 60 kHz. The power supply provides negative 6 V in buck-boost topology. The STEVAL-IHT005V2 can control 2 high power loads up to 2830 W thanks to the T1635H, a 16 A, 600 V high temperature Triac and up to 2050 W using the ACST1635-8FP, a 16 A, 800 V high temperature overvoltage-protected ACST device. The high power load control is based on phase-angle control. To limit inrush current and possible current peaks, the board features a soft-start routine and a smooth power change function for the high power loads. The STEVAL-IHT005V2 can also control 4 low power loads up to 100 W thanks to 3 ACS108-8S, 0.8 A, 800 V overvoltage-protected ACS devices and a Z0109, 1 A standard 4 quadrant 600 V Triac.
