Although silicon has been used in power electronics for a long time, silicon carbide technology is now finding its place in high power applications due to its superior material properties compared to silicon. The silicon carbide devices are now playing a vital role in the manufacturing of solar power inverters.
An inverter — which inverts DC power into AC power — is a general-use technology. One might argue that a solar inverter is used to convert DC power from a PV array to AC power . There are three primary types of PV inverter topology: micro inverter, string inverter and central inverter. Each is appropriate for different situations and scales.
Recently, silicon carbide (SiC)-based devices are used to improve the performance of PV inverters . The prices of SiC diode and metal–oxide–semiconductor field-effect transistor (MOSFETs) decrease by 10% per year. These SiC devices are replacing Si devices for PV inverter applications.
SiC power semiconductor devices can be used in a PV energy system as they can help eliminate several issues presently due to the material limitations of silicon. Commercially available high voltage SiC power MOSFETs can be used as a direct replacement for silicon IGBTs in the development of power electronics for solar applications.
The photovoltaic (PV) inverter is a major component in the solar energy conversion system. Its performance relies on the efficient design of power electronics.
When choosing a solar inverter for a solar panel, it is important to consider the inverter's ability to handle the panel's power rating with a 10% margin above the rated power. Operating above the rated power level can lead to long term reliability issues due to overloading of power devices.
