Forward Converter

This example shows the operation of a forward converter.

Contents

Description

The forward converter is a DC/DC converter that uses a transformer in series with the switching device (MOSFET in this example) to isolate the source from the load and to increase or decrease the input voltage depending on the transformer turns ratio. The theoretical transfer function of the forward converter is:

$Vout = n*D*Vin$

where $D$ is the duty cycle, and $n$ is the turns ratio of the transformer $(N_2/N_1)$
