6 FAQs about [Technical content of photovoltaic inverter inductor]

How a grid-connected photovoltaic inverter system works?

First, the mathe-matical model of grid-connected photovoltaic inverter system is built. Second, a multiloop interleaved control scheme is proposed for three-level boost maximum power point tracking converter to reduce the ripple of the inductor current and balance the capacitor voltage of DC bus.

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 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.

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.

What is a photovoltaic converter?

The converter is an ideal solution for applications requiring significant voltage gains, such as integrating photovoltaic energy sources to a direct current distribution bus or a microgrid. The structure of the introduced converter is comprised of an interleaved switched-inductor boost stage attached to the voltage multiplier cells stage.

What is a typical inverter?

A typical inverter comprises of a full bridge that is constructed with four switches that are modulated using pulse width modulation (PWM) and an output filter for the high-frequency switching of the bridge, as shown in Figure 1. An inductor capacitor (LCL) output filter is used on this reference design.
