6 FAQs about [Single-phase and dual-phase photovoltaic inverters]

Can a single-phase single-stage dual-Buck photovoltaic inverter reduce DC-link voltage Puls?

This paper proposes a single-phase single-stage dual-buck photovoltaic (PV) inverter with an active power decoupling (APD) strategy. Using this strategy, the dc-link voltage pulsating caused by a low-frequency power fluctuation in single-phase systems can be reduced without using a bulky dc-link storage.

What is PV single-phase inverter?

Photovoltaic (PV) single-phase inverters are widely used in the renewable power generation systems [ 1, 2 ]. There are two types of PV single-phase inverters, that is, isolated and transformer-less. The isolated inverters have no common mode leakage current, but the power density and the efficiency of them are low and cost of them is high.

Why does a single-phase inverter have a low-frequency power fluctuation?

In such single-phase inverters, the well-known low-frequency power fluctuation is expected to be absorbed by the dc link or the front-end converter. Otherwise, the problem regarding control instability can arise due to the dc-link voltage pulsating, which deteriorates the reliability of the PV system.

Can APD be universally applied in single-stage PV inverters?

The APD strategy can be universally applied in single-stage PV inverters regardless of the topology connected to the utility grid. To verify the proposed scheme, both simulations and experiments on a 2.1 kW single-phase single-stage dual-buck PV inverter are conducted.

How to improve performance of single-stage dual-Buck PV inverter?

The performance of single-stage dual-buck PV inverter can be improved by combining with the active power decoupling strategy. The active damping control assists to stabilize the control loop for the active power decoupling circuit. The active power decoupling can reduce the physical size of the dc-link storage.
