The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.

Can photovoltaic inversion and flexible arc suppression be used in grounding faults?

513 Abstract: This paper presents a novel approach that simultaneously enables photovoltaic (PV) inversion and flexible arc suppression during single-phase grounding faults. Inverters compensate for ground currents through an arc-elimination function, while outputting a PV direct current (DC) power supply.

Can arc-suppression devices compensate for fault current suppression in PV inverters?

Currently, research on fault current suppression in PV inverters is limited. Therefore, it is necessary to rely on arc-suppression devices to compensate for the fault current. Zhang et al. proposed a cascaded arc- suppression device that integrated flexible arc suppression by regulating zero-sequence currents.

How to achieve flexible arc suppression in a PV inverter?

To achieve flexible arc suppression in a PV inverter, the end of it should be connected in Y-type and the neutral point should be grounded. However, grounding creates a zero-sequence current loop, which leads to an increase in the zero-sequence current.
