By avoiding Centre tapping of the Fly back transformer, a more symmetrical waveform without any dc component in the output is obtained. This further improves Transformer Utilization Factor (TUF) and the voltage stress across various components is also reduced. The presence of fly back Transformer ...

This paper proposes a new approach for single-input multiple-output flyback converters operating in DCM and CCM by a small-signal averaged model. The averaged model is derived by presenting the piecewise-linear waveform for the inductor currents inside the converter. In DCM, the magnetizing ...
An unfolding type Flyback converter is common for PV applications. This paper proposes another topology without centre tapping which improves the wave shape of the load voltage. By avoiding centre tapping of the Flyback transformer, a more symmetrical waveform without any dc component in the output...
