Abstract:A SiC device-based dual-input Buck-Boost converter (DI-BBC) is analyzed and evaluated for high efficiency photovoltaic (PV) power system applications. The DI-BBC is built by cascading a dual-input Buck converter and a Boost converter. Independent maximum power point tracking (MPPT) of two PV inputs can be achieved within a wide PV voltage range. SiC devices are employed to reduce losses and improve conversion efficiency. Operation principles, modulation strategies, control and design considerations of the DI-BBC are analyzed in detail. Experimental tests were carried out to evaluate the performance of the DI-BBC-based PV system. © 2018 IEEE.
