FAQS 4

What happens if inverter side current is used for closed-loop control?

When the inverter side current is used for closed-loop control, the phase difference between the grid connected current and the grid voltage will be caused due to the filter capacitor, and the power factor will be reduced , and the LCL resonance peak cannot be well suppressed.

Can a three-phase PV inverter be controlled with a digital control board?

The proposed control architecture has been experimentally verified with three-phase three-level 40 kW PV inverter with a digital control board with TMS320F28343. An adoption of SiC device brings benefits on performances of three-phase photovoitaic (PV) inverters.

Can SVPWM modulation module drive a three-phase inverter?

This paper innovatively uses script module programming of plecs software to build the SVPWM modulation module which drive the three-phase inverter while realizing the closed-loop control. This research will be beneficial to the application of the new driving mode control inverter in practical production. 1.

How does a three-phase inverter work?

In this test case, STS is open ( x STS = 0 ) and the inverter caters to the power demand from the three-phase load. The three-phase loads are configured to operate in constant power mode with the current limit of 8 A. Measured data from the spectrum analyser are fetched and plotted for controller performance analysis.
