6 FAQs about [2 output inductors of photovoltaic inverter]

What is the best coupled inductance for PV inverters?

The best coupled inductance can then be determined by observing the minimum power loss from Pc (EUR). It is observed from Figs. 6a and b that the best coupled inductances for 1.5 and 2.5 kW PV inverters are 3.58 and 2.92 mH, respectively.

Why is a coupled inductor a good choice for an inverter?

The coupled inductor with larger inductance is beneficial to improve the inverter output current quality but instead of causing additional power loss due to the increased series parasitic resistance. Conversely, once the inductance is turned down, the part of the filter power loss caused by the growing ripple current becomes gathering.

Which solar inverter is suitable for direct connection to LV grid?

Can a PV inverter be used in a low voltage grid?

The target application is large string-type inverters with high efficiency requirements. The PV inverter has low ground current and is suitable for direct connection to the low voltage (LV) grid. Experimental results for 50 and 100 kW prototypes demonstrate the high efficiency that is possible with SiC technology.

What is a voltage source inverter?

The inverter is normally the key interface between the solar cells and the AC load. The output voltage of the PV systems is generally low. Consequently, inverters need to have the ability to boost the output voltage of PV in order to maintain a stable AC voltage for the load. The traditional voltage source inverter is a step-down inverter.

What is a PV inverter?

As clearly pointed out, the PV inverter stands for the most critical part of the entire PV system. Research efforts are now concerned with the enhancement of inverter life span and reliability. Improving the power efficiency target is already an open research topic, as well as power quality.
