An L filter or LCL filter is usually placed between the inverter and the grid to attenuate the switching frequency harmonics produced by the grid-connected inverter. Compared with L filter, LCL filter has better attenuation capacity of high-order harmonics and better dynamic characteristic [2, 3].
A LCL filter is often used to interconnect an inverter to the utility grid in order to filter the harmonics produced by the inverter. This paper deal design methodology of a LCL filter topology to connect à inverter to the grid, an application of filter design is reported with m-file in Matlab.
INTRODUCTION In the photovoltaic grid-connected inverter based on inductor capacitance inductor (LCL) filter, the filter parameters are designed according to the rated power of the grid-connected inverter [ 1 ]. However, the power generated by Photovoltaic (PV) modules is closely related to the intensity of solar radiation.
The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.
Abstract Low power grid-connected inverters using L-type filters have the advantages of simple structures. However, due to the weak suppression of higher harmonics and the fact that the
