6 FAQs about [Photovoltaic inverter interleaving parallel technology]

What is interleaved fly-back inverter topology for photovoltaic applications?

The main aim of this paper is to design and analysis of interleaved fly-back inverter topology for photovoltaic applications. The purpose of this inverter topology is to increase the output voltage of PV module and increase the overall efficiency of the system.

Can parallel interleaved inverters be increased?

The capacity and equivalent switching frequency of parallel interleaved inverters can be increased, but there are problems with neutral point potential balance and parallel bridge circulating current. This paper regards the parallel three-level inverter as a five-level inverter and five-level space vector integrated modulation is applied.

What is a parallel PV inverter scheme?

The proposed scheme is for multiple parallel inverters to assist their seamless transfers between islanded and grid-connected modes. An example system for explaining the scheme is given in Fig. 1 with two parallel PV inverters connected to the point of common coupling (PCC) and to the grid through static switches (SSs).

Why should you choose a parallel 3LT 2 inverter?

However, in the parallel system, some of parallel inverter modules can be switched off in this case, while using the remaining converter to deliver power to the grid. By using this method, the efficiency of the system can be improved. Therefore, the parallel 3LT 2 Is can satisfy the higher power rating and efficiency.

Is a parallel three-level inverter a 5-level space vector integrated modulation?

This paper regards the parallel three-level inverter as a five-level inverter and five-level space vector integrated modulation is applied. On this basis, a neutral-point potential control strategy based on the mid-point charge to calculate the adjustment factor k is proposed.

What are the advantages of a three-level inverter?

The three-level inverter can reduce the total harmonic distortion (THD). The T-type topology, which is one of many three-level topologies, has an advantage regarding efficiency compared with the neutral-point-clamped (NPC) type [1 - 3]. Compared with the two-level inverter, the 3LT 2 I reduces the switching loss and switching noise [4 - 6].
