Özet

In this study, boost-type Cuk's PWM-resonant converter is compared with the conventional boost converter in terms of required inductor size, efficiency, and dynamic response. The inductor sizes required by both topologies are selected based upon the core geometrical constant design method. It is found out that the PWM-resonant converter offers a significant reduction in the required inductor size. The efficiency measurements are made in simulation by modeling the lossy elements and the simulation results show that the conventional boost converter has a better efficiency characteristic. The dynamic responses of both converters are also compared under closed-loop control and the PWM-resonant converter shows a faster transient regime with lower overshoots.
