Hard and Soft Switching Geometries For Operations of the MOSFET Used For the SMPS

The paper re-validates in between hard and soft switching activities, geometries and characteristics generated by the switching actions of the MOSFET used for the boost converter as switched mode power supply (SMPS). Switching curves are reshaped by the published literature. In the hard switching, the parasitic effects, stresses and switching power losses across the power semiconductors are more pronounced than soft switching operations of the SMPS. So, the soft switching converter for high switching frequency needs for the high power density, compact size, performance evaluations and improvements in a platform of SMPS technology.
