A Push Pull Converter is dc to dc converter that provides an output voltage that can be either less than or greater than the dc input voltage VS. The push-pull converter give multiple outputs with single input. This can be achieved by changing the winding’s turns ratio of the transformer. Push-pull designs are popularly used in
