| Abstract |
The self-consumption of PV-systems can be increased with a battery. The proposed three-phase inverter provides three independent DC inputs that can each be connected to a battery or a PV-string. The innovative topology allows energy flow in each direction at a very high efficiency (> 98 \% in each converter stage). The application of SiC transistors leads to a higher switching frequency (48 kHz) compared to commercial systems. The resulting filter elements such as inductors and capacitors are PCB mountable. Thus a highly integrated demonstrator was developed. The system is proposed in detail in this paper. |
