Analysis and Validation of a Non-Isolated Cuk Converter in Continuous Conduction Mode

As per the control-to-output voltage transfer function Tp for lossless ´Cuk converter, the conjugate complex zeros are on the right-half plane zeros. The behavior of zeros for variation in the duty cycle D and load resistance RL is observed. As the duty cycle varies from 0 to 1, the right-half plane zeros of the control-to-output voltage transfer function Tp for lossless ´Cuk converter start as conjugate-complex zeros from the y-axis and intersect at the x-axis changes into real zeros. Whereas one zero moves close to the origin and the other one goes to infinite. As the load resistance varies from 1Ω to 100Ω, the right-half plane zeros of the control-to-output voltage transfer function Tp for lossless ´Cuk converter moves towards close to the origin.
