Forward Converter Circuit Diagram· The forward converter said to be in Freewheeling Mode when the transistor is in OFF state. As the transistor turns off, the current of windings of transformer falls to zero (ideally). D1 will be reversed biased in this condition, therefore separates the output section of circuit from the transformer …
