By definition, "The Ćuk converter is a type of DC/DC converter that has an output voltage magnitude that is either greater than or less than the input voltage magnitude"

So I was wondering how I can get: a) An output voltage lower than input voltage b) An output voltage higher than input voltage

Also, for a Cuk converter, is it possible to easily switch between low and high output voltage configurations, without changing the entire circuit?

  • \$\begingroup\$ The duty cycle (and input polarity) of your input can really determine how you can get a higher or lower output... That's really the whole point of of Cuk converter. The main difference between a standard buck-boost and a Cuk converter is that a buck-boost transfers the energy on the inductor whereas the Cuk transfers the energy on the capacitor. \$\endgroup\$

  • \$\begingroup\$ Oh okay. But wouldn't I be able to get a lower voltage/ higher voltage output for a buck and a boost converter- again just by varying the duty cycle? How is this different different from varying the duty cycle for a Cuk converter? \$\endgroup\$

  • \$\begingroup\$ Now, I need to point you to a Wikipedia page about this. There are formulas for fundamental design. \$\endgroup\$
