Please note the presence of the output inductor which is necessary in all buck-derived topologies:Īs shown in the below sketch, the converter operates in a heavy continuous conduction mode (CCM). You can find a comprehensive description of the push-pull converter in the Google preview of this book.Įdit: to avoid confusion, I've added below a SIMPLIS simulation using a simple pulse width modulator. The below simulation shows the waveforms: This is the flat portion missing in your drawing. The magnetizing current keeps circulating in the secondary side but because there is no voltage across the primary winding, the magnetizing current pauses. In a push-pull converter, when both switches are off, there is a net 0-V across the transformer primary side because both diodes are conducting for the output inductor demagnetization phase.
