Controlling of DC-DC converter is vital task in power conversion. DC-DC converters are used in many applications like solar charger, computer power supplies, switching mode regulators, aircrafts etc. Focus of this paper is to model a controlling system for buck converter which controls output of buck converter constant instead of changing load and input supply to buck converter. Controlling met...

The DC transfer functions for the buck, boost, and Cuk PWM DC-DC converters in continuous conductionmodearell, l / ( l D ) , and-D/( l -D) respectively, ,where D is the duty cycle. Therefore. it is reasonable to expect that the Cuk PWh4 DC-DC converter circuit [l] can be synthesized by cascading boost and buck converter circuits.

In this paper fractional order averaged model for DC/DC Buck converter in continues condition mode (CCM) operation is established. DC/DC Buck converter is one of the main components in the wind turbine system which is used in this research. Due to some practical restriction there weren’t exist input voltage and duty cycle of converter therefor whole of the wind system was simulated in Matlab/Si...

Single-Stage transformerless AC/DC converter received much attention in the universal line application. Unlike the existing converters a new high step-down transformerless single-stage single-switch AC/DC converter is proposed. The topology integrates a buck-buck-boost converter with low intermediate bus and output voltage. The converter utilizes a buck converter as a PFC cell and buck-boost co...
