Description
The STEVAL-ISF002V1 demonstration board
provides platform for evaluating the capabilities of
STMicroelectronics’ STW23NM60N MDmesh™
power MOSFET, and the TD352 advanced
IGBT/MOSFET driver.
The board also demonstrates ST’s
STM32F103ZE microcontroller in digital power
factor corrector application. The performance of
the MCU in this design is comparable to standard
continuous-mode PFC dedicated monolithic ICs,
while retaining sufficient microcontroller
resources (such as program memory and CPU
computational capability) to execute additional
complex operations.
The system is designed to offer high performance
in terms of PF, THD and DC output voltage ripple.
For less demanding applications, the size of
power components on the PFC power board can
STEVAL-ISF002V1
be reduced to implement a more cost-effective
solution. Unlike monolithic ICs, this digital
approach allows the application of sophisticated
control algorithms and easier adjustment of
system parameters to meet customer
requirements.
Thanks to an MC connector on the PFC power
board, it can be interfaced with several ST MCU-
based boards, particularly those developed for
motor control. The on-board off-line SMPS based
on ST’s VIPer12A-E is used to generate the 15
VDC voltages necessary to supply the drivers in
the power board. This board also provides 5 V to
supply any control stage supplied via the MC
connector.
