6 FAQs about [Photovoltaic inverter series inductor]
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.
What is a switched inductor active network inverter?
Switched Inductor active network inverter provide high-boosting-ratio, reduced voltage stresses and moderate-efficiency. Conventional inverters isn’t able to offer a high-voltage gain and the thin turn-off time will cause large peak-current and significant conduction and switching-losses.
Why do inverters need two independent power supplies?
The inverter requires two independent input power supplies and two independent boost inductors, which leads to low utilization rate of power source and the large volume of the circuit. Also, the voltage gain of the inverter circuit is low.
What is a switched inductor in a transformerless boost inverter?
Switched inductor is the combination of a pair of equal valued inductors and multiple passive (diodes) elements. Thus, this switched inductor concept is added to the transformerless boost inverter so that it has characteristics of high gain, high efficiency, high integration, few power devices, less switching losses and easy to control.
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.
