Topologies

Technical Article Common PowerSupply Topologies

Technical Article CONTENTS • Introduction • Buck • Boost • Flyback The essential difference between the three topologies is that the buck has an output voltage lower than its input, the boost has an output voltage higher than its input and theflybackcan have an output voltage either ...

Network Topology Generators: Degree-Basedvs. Structural

For all topologies, we compute link values using shortest path routing. In addition, for the AS and RL topologies, we use the sim-plepolicymodel described in Section 3.2.1 to evaluate link values using policy-constrained paths.
