There are about 14 basic topologies (basic block diagrams) commonly used to implement a switching power supply. Each topology has unique properties which make it best suited for certain applications.

Dual switch QR flyback topology and secondary synchronous rectification is ... The validity of the proposed topology is verified with a 90W prototype power supply. Introduction: Because of the ...

A switching power supply is more efficient than a linear power supply because ... classified based on circuit structure or input/output configuration. Non-isolating topologies are simpler designs that ...
