What Makes SiC MOSFETs
the Perfect Solution for
String Inverters and
Energy Storage Solutions?

of energy buffers to stabilize the grid. Figure 1 shows the forecast for this trend worldwide according to region.
High efficiency has a higher value now, as energy is passed back and forth through the inverters; hence, losses might be counted multiple times. Thus, the benefit of SiC-based invert- ers with a higher efficiency of about 1%, or up to half of the losses compared with Si-based solutions, is of major com- mercial value for the operator of such “green” power plants.
for energy and cost savings, particularly when bidirectional power conversion is required. Bidirectional power flow is essential to connect large-scale storage systems to commer- cial string-inverter–based power plants. This trend is rapidly gaining momentum as the growing number of renewable energy sources in the energy mix forces the implementation
