High-order filters, such as LCL, are more commonly employed in grid-connected inverters (GcIs) an interference element for the better attenuation of switching harmonics. However, LCL filters may have resonance poles and antiresonance zeros frequency response with inverter side current. This affect stability system limit control bandwidth simple single-loop PI control. becomes severe introductio...

For the controller design and stability analysis of power electronic converters, Bode criterion its subsequent revisions are most practical tools. However, even though control converter is usually implemented in a microprocessor, none these methods infallible when applied to discrete system. This article therefore proposes new criterion, named Discrete Generalized Criterion (DGBC). method based...

In this paper a solar photovoltaic (PV) system with maximum power point tracking (MPPT) for domestic low applications. The proposed contains PV array which provides electrical power, while DC/DC converter is incorporated to regulate the derived from panels. Fuzzy logic control (FLC) based MPPT has been proposed. To convert DC voltages and currents obtained Solar panels AC currents, Neutral clam...

Abstract Photo-voltaic inverts usually use LCL filter for filtering, and will bring resonance problems to the system. This paper focuses on invert-er side current feedback control (invert-er feedback, ICF). proposes a method suppressing of photo-voltaic clusters based capacitor voltage feed-forward. First, establish ICF mathematical model HPF CVF under weak grid, qualitatively analyze mechanism...

The lateral collateral ligament (LCL) complex of the elbow plays a crucial role in the stability of the elbow joint, especially to varus loads. Deficiency of particularly the lateral ulnar collateral component of the LCL can lead to chronic posterolateral rotatory instability, which can be functionally debilitating and can lead to a rapid onset of early degenerative arthritis. Commonly, in the ...

Abstract Distributed generators are playing a vital role in supporting the grid ever-increasing energy demands. Grid code regulation must be followed when integrating photovoltaic inverter system to grid. The paper investigates and analyzes controller model for grid-connected PV inverters inject sinusoidal current with minimum distortion. To achieve better tracking disturbance rejection, DSP-ba...

Localised cutaneous leishmaniasis (LCL) is the most common form of cutaneous leishmaniasis characterised by single or multiple painless chronic ulcers, which commonly presents with secondary bacterial infection. Previous culture-based studies have found staphylococci, streptococci, and opportunistic pathogenic bacteria in LCL lesions, but there have been no comparisons to normal skin. In additi...

AIM To prepare RGD-modified long circulating liposome (LCL) loading matrine (RGD-M-LCL) to improve the tumor-targeting and efficacy of matrine. METHODS LCL which was prepared with HSPC, cholesterol, DSPE-PEG2000 and DSPE-PEG-MAL was modified with an RGD motif confirmed by high performance liquid chromatography (HPLC). The encapsulation efficiency of RGD-M-LCL was also detected by HPLC. MTT as...
