6 FAQs about [Inductor cost in photovoltaic inverter]

Why do solar PV inverters use DC link inductors?

This element reduces the lifetime and increases the cost of the photovoltaic system , . Thus, the solar PV inverter desires to use reduced capacitance value. Boost inverter uses dc link inductors to maintain a constant current, thus less capacitance value is used in dc link.

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 do solar PV inverters use a lower capacitance value?

Since capacitor value directly depends on the maximum power, most of the inverters use electrolytic capacitors parallel to the PV module. This element reduces the lifetime and increases the cost of the photovoltaic system , . Thus, the solar PV inverter desires to use reduced capacitance value.

How does a PV inverter work?

PV Inverter systems require DC/DC boost converters, as part of the Maximum Power Point Tracker (MPPT), to adjust the PV panel output voltage to the required DC-link voltage level. This is then input into DC/AC converters which deliver the solar energy to the public grid. Figure 3. High-level block diagram of PV inverter

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.

How a solar PV inverter has a higher lifetime?

Higher lifetime can be obtained by using film capacitors in boost inverters. Apart from that, source side electrolytic capacitor is replaced by multiple ac film capacitors for energy storage purpose as shown in Fig. 10, Fig. 12. Thus, boost inverters shows the desired characteristics of solar PV inverter. Fig. 21.
