150 W inverter featuring L639x and STGD3HF60HD for 1-shunt based sinusoidal vector control and trapezoidal scalar control
The 150 W inverter power stage board features the L639x and STGD3HF60HD for both field-oriented control (FOC) of permanent magnet synchronous motors (PMSM) and trapezoidal scalar control of brushless DC (BLDC) motors. Also referred to by the order code STEVAL-IHM032V1, this 3-phase inverter is designed to perform both the FOC of sinusoidal-shaped back-EMF PMSMs and trapezoidal control of BLDC motors with or without sensors, with nominal power up to 150 W. The flexible, open, high-performance design consists of a 3-phase inverter bridge based on:
■ The STGD3HF60HD (4.5 A, 600 V) very fast IGBT in a DPAK package, with ultrafast recovery diode
■ The L639x devices which are part of the latest high-voltage half bridge gate driver family featuring an integrated comparator for implementation of hardware protection (i.e. overcurrent, overtemperature, etc.)
■ An embedded operational amplifier suitable for advanced current sensing
The system 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. As an alternative to the STGD3HF60HD, the STD5N52U power MOSFET, STGD6NC60HD IGBT device may be used on the board without replacing the switch driving network.
The board is compatible with 110 and 230 Vac mains, and includes a power supply stage with the VIPer12AS-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 with STM3210xx- EVAL (STM32 microcontroller demonstration board), STEVAL-IHM022V1 (high density dual motor control demonstration board based on the STM32F103ZE microcontroller), and with STEVAL-IHM033V1 (control stage based on STM32F100 microcontroller suitable for motor control), through a dedicated connector.
