100 W 3 phase inverter featuring L6390 and STD5NK52ZD
for vector control STEVAL-IHM021V1
Introduction
The 100 W 3-phase inverter featuring the L6390 and STD5NK52ZD for field-oriented control
(FOC) of permanent magnet synchronous motors (PMSM) demonstration board (also
referred to by its order code STEVAL-IHM021V1) is a 3-phase inverter designed to perform
the FOC of sinusoidal-shaped back-EMF PMSM - with or without sensors - with nominal
power up to 100 W.
The device’s flexible, open and high-performance design consists of a 3-phase inverter
bridge based on the STD5NK52ZD-1 power MOSFET in IPAK package and L6390 device,
the latest high-voltage half-bridge gate driver family featuring an integrated comparator for
hardware protection implementation (for example, against over-current, over-temperature,
etc) and an embedded operational amplifier suitable for advanced current sensing. The
system has been specifically designed to achieve accurate and fast 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 VIPer12AS-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.
