6.3) POWER STAGE - FORWARD CONVERTER
The power stage is provided by a single switch type DC/DC Forward
converter.
The functional diagram of this converter is illustrated in the figure
below.
Forward Converter
The control logic controls the electronic power switch (MOSFET)
appropriately so that the output current has the required dynamic
range and the transformer does not become saturated.
The Forward converter made by Selco provides a suitable transfor-
mer resetting circuit in order to improve the performance of the sy-
stem and to have better control of the output current.
The transformer, in addition to adjusting the voltage and current le-
vels, also makes it possible to obtain the galvanic isolation between
the user and the mains required by the regulations in force.
