Abstract :
In this work a two-stage boost converter circuit is investigated. Relations for the dimensioning of the converter elements are given and a realistic converter model is derived and presented using state-space description. The transfer functions for the output voltage depending on the duty ratio and the input voltage are calculated and topologies of possible voltage control systems are suggested. The proposed converter can be used to boost up the battery supply voltage e.g. for electric auxiliary drives in automotive applications.
