Abstract
Linear controller design for a large dc gain converter
Highlights
Cascading two or more boost converters can be used to obtain a higher conversion ratio but this method needs a more complex controller (Rahimi and Emadi, 2009)
When switch is closed (Fig. 2), L is charged by voltage source, D2 is forward bias while D1 and D3 are reverse bias
C1 and C2 are charged very quickly since there is no resistance in their path except of parasitic resistances
Summary
Cascading two or more boost converters can be used to obtain a higher conversion ratio but this method needs a more complex controller (Rahimi and Emadi, 2009). Plenty of high voltage gain topologies has been introduced Speaking, using derivative term is not so common in power electronics converters control. A P or PI controller is all that is required. This paper designs a controller for one of the recently published topologies (Li et al, 2015)
