6 FAQs about [Photovoltaic inverter inductor box]

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.

What are the different types of PV inverters?

There are four configurations commercially accepted [26 – 30]. Central-plant inverter: usually a large inverter is used to convert DC output power of the PV array to AC power. In this system, the PV modules are serially string and several strings are connected in parallel to a single dc-bus. A single or a dual-stage inverter can be employed.

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.

How does a PV inverter state machine work?

The inverter state machine then sequences to checking for DC voltage. To feed current into the grid the DC voltage (which in case of PV inverters is provided from the panel or panel plus some conditioning circuit), it must be greater than the peak of the AC voltage connected at the output of the inverter.

What type of inverter can be used?

A single or a dual-stage inverter can be employed in this kind of configuration. Module-integrated inverter: each module has a small inverter, and each one is connected in parallel forming an ac-bus, which is connected to the AC grid. Once more, a single or a dual-stage inverter can be used.

What is a DC-AC inverter?

All the control, MPPT, and grid-current are implemented in the DC-AC stage (inverter) that consists of a three-phase bidirectional power flow PWM voltage source inverter (VSI3). This is the principal power electronics circuit of a Three-Phase Grid-Connected PV Power System. Figure 8 shows the basic idea of a modified dual-stage inverter.
