6 FAQs about [Modulation method of photovoltaic inverter]

Which modulation technique is used to control SFI (solar fed inverter)?

Among these modulation techniques, the proposed SFI (Solar Fed Inverter) controlled with Sinusoidal-Pulse width modulation in experimental result and simulation of Digital-PWM results is verified under the lowest THD level.

How to boost the voltage of PV modules?

In the literature, various modulation techniques have been developed that help to boost the voltage of the PV modules by implementing shoot-through (ST) in which the upper and lower switches of an inverter conduct simultaneously and short-circuit occurs. Various optimised modulation techniques have been implemented to enhance its performance.

What are the different types of modulating schemes used in PV applications?

In order to differentiate the different types of modulating schemes for converters used in PV applications, there are various factors such as complexity, voltage boost capability, D s h in terms of modulation index, voltage stress across capacitor (V C 1 / V s), normalized peak phase voltage (V ϕ 1 / V s), switching loss, and efficiency [87, 98].

What is a photovoltaic converter?

Photovoltaic (PV) is a promising way to meet the increasing global energy demand due to its sustainability, efficiency, and cost-effectiveness. For the wide-scale adoption of PV systems, converters with reliable input sources, stable control strategies and appropriate modulation techniques must be designed.

How to configure a PV inverter?

Conﬁguration of PV Inverters ]. Among them, the most commonly used conﬁgurations are the series or parallel and series connections. If the PV panels are attached in series with each other it is called a string, and if these are then connected parallel it forms an array. Basically, the PV modules are arranged in four ].

Can a parallel inverter be modulated separately?

If the inverter is modulated separately, the benefits of the parallel topology cannot be fully exploited. The interleaved parallel connection between two three-level inverters can be realized using the interaction of the coupled inductors, which can suppress the circulating current.
