Abstract EN
Compared with L-type filter, LCL-type filter is more suitable for high-power low-switching frequency applications with reducing the inductance, improving dynamic performance.
However, the parameter design for the LCL filter is more complex due to the influence of the controller response performance of the converter.
If the harmonic current around switching frequency can be fully suppressed, it is possible for inverter to decrease the total inductance as well as the size and the cost.
In this paper, the model of the LCL filter is analyzed and numerical algorithms are adopted to analyze the stability of the closed-loop control system and stable regions are deduced with different parameters of LCL filter.
Then, the minimum sampling frequencies are deduced with different conditions.
Simulation and experimental results are provided to validate the research on the generating mechanism for the unstable region of sampling frequency.
