Output currents analysis of multi and single phase noninverting buck-boost converters

Matej BEREŠ, Dobroslav KOVÁČ

In the paper, an interleaved noninverting buck-boost converter is presented and compared with a single phase one.

The converter consists from six same buck-boost modules which are operating in parallel. The topology of multiphase buck-boost converter is suitable for many applications where high power with low interference is needed. Both single phase and multiphase converters are controlled with an ARM (Advanced RISC Machine) microcontroller in experimental environment. This article describes detailed operation of the single-phase and multiphase converter and provides simulation and experimental results of output current ripple. For achieving valid results the same electrical components with same value are used.
