FAQs about Common-mode current of photovoltaic inverter
What is a transformerless photovoltaic (PV) inverter?
An essential requirement for transformerless photovoltaic (PV) inverters is the suppression of common-mode (CM) ground leakage currents. Transformerless PV inverters normally provide a voltage step-up capability to extend energy harvesting from PV arrays.
Can a PV inverter be used without an isolation transformer?
The leakage current level is used for the determination of the suitability of the investigated PV inverter topology for grid connec-tion without isolation transformer. The problems of increasing electricity demand by the unabated population growth can be solved by employing sustainable distributed generation tech-nologies.
Why is ground leakage a critical requirement for PV inverters?
In addition to high efficiency, the suppression of common-mode (CM) ground leakage currents is another critical requirement for PV inverters. Ground leakage currents can flow in transformerless inverter systems because of the existence of parasitic capacitances between the solar cells of the PV array and the ground.
How does a transformerless PV inverter work?
In dual-mode time-sharing transformerless PV inverter topologies, a step-up (boost) stage operates alternatively with a step-down (buck) stage to create a rectified sine wave DC-link voltage, which is then unfolded to the grid by an H bridge.
