This paper presents an improved interleaved boost converter (IBC) with optimal Type-III controller by utilizing voltage mode control. Due to the presence of several power switches in parallel path, the degree of freedom has been increased in IBC. Also, the IBC produces lower output voltage ripples, so the size and losses of the output filter can significantly be reduced compared with conventional...
This paper reflects the study of a Power-Factor-Correction (PFC) boost converter's nonlinearity. A peak current controlled boost converter is simulated in continuous conduction mode (CCM) to study the dynamics through the bifurcation diagrams. The study shows that with changes of certain parameters the bifurcation and chaotic state may occur. The bifurcation diagrams indicate the stable zone of various...
DC-DC power supplies are used in almost every sphere of engineering like PC/laptop, chargers, spacecraft, HVDC transmission etc. A steady source of voltage is required irrespective of any changes in line, load condition & parametric uncertainties for their application. The steady state behaviour of converter can be explained by the topology of converter and the controller has taken an important...
