Board description

The STEVAL-ISF001V2 can be used for several kinds of applications:

●

Inverter for motor control

●

Air conditioning system

●

Welding machine DC power supply section.

This demonstration board offers customization options as well, making it an excellent choice

as an original platform for a more complete and dedicated system. Special care has been

taken during the layout process to provide a very low level of interference. Considering the

power delivered and the level of current present on the board, we advise no major

modification of the layout for customization of the system in order to avoid noise that could

cause the board to malfunction.

The board includes:

●

An input stage composed of a 25 A power rectifier bridge

●

An input filter stage necessary to comply with the EMC emission levels

●

A control stage composed of the L6563S

●

A power stage composed of a power MOSFET and power ultra-fast diodes

●

A power inductor designed and manufactured specifically for this application

●

An output filter stage composed of an electrolytic capacitor sized to have the ripple

required by the specification.
