100 W 3-phase inverter demonstration board using the
L6390 and STD5N52U for vector control
Introduction
The 100 W 3-phase inverter demonstration board features the L6390 and STD5N52U for
field-oriented control (FOC) of permanent magnet synchronous motors (PMSM). Also
referred to by order code STEVAL-IHM021V2, this 3-phase inverter is designed to perform
the FOC of sinusoidal-shaped back-EMF PMSMs with or without sensors, with nominal
power up to 100 W. The flexible, open, high-performance design consists of a 3-phase
inverter bridge based on:
■ the STD5N52U power MOSFET in a DPAK package, with enhanced fast body-drain
recovery diode
■ the L6390 device, which is 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 STD5N52U, the STGD6NC60HD or
STGDL6NC60DI IGBT devices 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 VIPer12A-E (in buck configuration) to generate the +15 V and +3.3 V supply voltage
required by the application. Finally, the board can be interfaced with the STM3210B-EVAL
(STM32 microcontroller demonstration board) through a dedicated connector.
