How silicon carbide helps to get the best from a solar PV
Silicon Carbide (SiC) switches are an obvious choice to replace the IGBTs in new designs. They have lower switching and static losses and certainly work well at much higher frequencies, reducing passive components size. A simple solution would be SiC cascode devices in a two-level inverter (Figure 2).
