In recent years, several LCL filter design methods for different converter topologies have been published, many of which use analytical expressions to calculate the ideal converter AC voltage harmonic spectrum. This paper presents the LCL filter design methodology but the focus is on presentation and validation of the non-iterative filter design method for a grid-connected three-phase two-level PWM-VSC. The developed method can be adapted for different converter topologies and PWM algorithms. Furthermore, as a starting point for the design procedure, only the range of PWM carrier frequencies is required instead of an exact value. System nonlinearities, usually omitted from analysis have a significant influence on VSC AC voltage harmonic spectrum.

Design and Control of an LCL Filter Based Three Phase Active Rectifier (1)

AbstractThis paper proposes a step-by-step procedure fordesigning the LCL filter of a front-end three-phase active rectifier. The primary goal is to reduce the switching frequency ripple at areasonable cost, while at the same time achieving a high-perfor-mance front-end rectifier as characterized by a rapid dynamicresponse and good stability margin. An example LCL filter designis reported and a filter has been built and tested using the valuesobtained from this design. The experimental results demonstratethe performance of the design procedure both for the LCL filterand for the rectifier controller. The system is stable and the gridcurrent harmonic content is low both in the low- and high-fre-quency ranges. Moreover, the good agreement that was obtainedbetween simulation and experimental results validates the pro-posed approach. Hence, the design procedure and the simulationmodel provide a powerful tool to design an LCL-filter-based activerectifier while avoiding trial-and-error procedures that can resultin having to build several filter prototypes.

Design and control of an LCL-filter based three-phase active rectifier Abstract: The aim of the paper is to propose a design procedure for an LCL-filter in a front-end three-phase active rectifier. The main goal is to ensure a reduction of the switching frequency ripple at a reasonable cost and, at the same time, to obtain a high performance rectifier. In this paper a step-by-step procedure for designing an LCL-filter is proposed and verified by simulations and experiments.

The most important feature of active rectifier circuits is the ability to adjust the power factor and DC bus voltage, when compared to diode rectifiers. However, odd current harmonics occur in the grid since hard switching state occurs in the active rectifier circuit. A filter should be used on the grid side to reduce the current harmonics. Although there are many types of filters, one of the most suitable filter types is LCL filter when considering the factors such as cost and size. In this study, LCL filter design calculation is performed and PSIM simulation results of active-reactive power controlled LCL filter proportional resonant PR current controlled single phase active rectifier circuit is given.

Голос Грега Хейла эхом отдавался в ее сознании: Сьюзан, Стратмор меня убьет, коммандер влюблен в. Она подошла к огромному круглому порталу и начала отчаянно нажимать кнопки. Дверь не сдвинулась с места. Она пробовала снова и снова, но массивная плита никак не реагировала. Сьюзан тихо вскрикнула: по-видимому, отключение электричества стерло электронный код. Она опять оказалась в ловушке. Внезапно сзади ее обхватили и крепко сжали чьи-то руки.

 Что с тобой? - удивленно спросил Хейл. Сьюзан встретилась с ним взглядом и прикусила губу. - Ничего, - выдавила. Но это было не. Терминал Хейла ярко светился.
