What is a power electronic based inverter?
In both standalone or grid-connected PV systems, power electronic based inverter is the main component that converts the DC power to AC power, delivering in this way the power to the AC loads or electrical grid.
Which type of inverter is used in VSI?
Nowadays, inverters are mostly using either power IGBTs or MOSFETs. Power MOSFETS are used for high frequency and low power switching operations, whereas IGBTs are employed when high power and low-frequency operations is required. Between the CCM and VCM mode of VSI, the CCM is preferred selection for the grid-connected PV systems.
What is a safety feature of a PV inverter?
Islanding is the process in which the PV system continues to supply power to the local load even though the power grid is cutoff . A safety feature is to detect islanding condition and disable PV inverters to get rid of the hazardous conditions. The function of inverter is commonly referred to as the anti-islanding.
