In first part I introduce few base switching regulator topologies and write for them equations that are important for their performance. More in detail I introduce Ćuk and SEPIC topologies and draw schematic circuits for them. I then simulate those circuits and compare efficiency, noise and transient response for them. I also make this circuit in real practice and perform mentioned measurements. Then I compare simulated and measured values and find out advantages of Ćuk regulator in efficiency and noise levels, and advantages of SEPIC regulator in transient response and thermal management.
