Title
Extreme high efficiency non-inverting buck-boost converter for energy storage systems
Abstract
This paper presents a high efficiency bidirectional non-inverting buck-boost converter for energy storage systems. A new control concept for achieving high efficient power conversion within a wide power range is introduced. A 3 kW prototype is designed and tested with Si-and SiC-MOSFETs. Experimental results show that the prototype achieves a minimum efficiency of more than 98% at 5% load and a maximum efficiency of more than 99.4% at the operating points where the output voltage approaches the level of the input voltage.
