Features
Description
The STEVAL-ISW001V1 demonstration board is
a complete 2.5 kW arc welding system capable of
135 A of welding current. It is designed for small
industrial applications and domestic use for do-it-
yourself applications. The system is ready-to-use
and designed to perform manual metal arc (MMA)
welding of iron and steel, following MMA process
recommendations.
The purpose of the demonstration board is to
provide a platform for evaluation of
STMicroelectronics’ silicon devices in high
power/current applications, where the robustness
and efficiency of the silicon devices used are the
keys to a reliable system.
The complete system consists of two boards. One
is a power board, where all the power conversion
devices needed for the application are mounted.
The other is a small control board that includes
the PWM generator and analog control circuitry
necessary to manage the MMA arc welding
process.
The layout of the power board is designed to
achieve a low level of interference, taking into
consideration the high power delivered and the
current levels present on many parts of the board.
The shape of the board and the position of the
magnetic/silicon components mounted on it are
optimized to guarantee sufficient air flow to the
parts involved in heat dissipation.
